This invention addresses a method of scanning and self organization that is programmed into the base station which then will automatically avoid mutual interference and move the use of radio channels from one base station to another to move network capacity to where it is needed through a process called 'abandonment'.

Self organizing cellular networks

This invention addresses a method of whereby a cellular base station can scan the radio band to identify radio channels that are not in use, then claim those un-used radio channels for use to transmit and receive radio signals. A plurality of such radio base station could then comprise a cellular radio network, which channel planning and frequency re-use has become autonomous and self organizing. The present disclosure aims to further expand the utility and function of such self organizing cellular networks by including a user interface to the base station by which the operator can define the radio spectrum boundaries that the base station is authorized to operate within and to further set operational rules for the use of sub-sections of that defined spectral boundary.

Band masking of self organizing cellular networks

A system and method for substantially reducing average transmit power by omitting the transmission of a majority of pulses by using a modified run length coding to reduce signal power. By lowering the average power, an opportunity is presented to either decrease the total power drawn by the transmitter (battery life) or raise the peak power of all symbols (Eb/No), thereby increasing range of a RF transmission system.

A system and method of carrier less modulation is described in this disclosure that uses SAW filters as a modulator in addition to their conventional use as filters for band limiting an UWB system. This system and method is primarily designed to be used with any integer cycle, ultra-wide band or impulse type modulation and more particularly is designed to work with a method of modulation named xMax. This technique exploits the impulse response of the SAW filter producing a carrier less impulse radio system with limited bandwidth, low average power, but high peak power.

This invention addresses the need to transport high bit-rate data to multiple users, or between users, over wired and wireless means. Specifically, this disclosure describes a new method of enabling communication from mobile phone to mobile phone when no network services are available as long as radio contact between the mobile handsets is possible by reserving un-assigned timeslots in the medium access control protocol super frame structure.

A system and method to detect broadband pulses in the presence of multiple strong narrow band interferers is disclosed whereby a picket fence filtering method is used to detect and ignore the signal at the precise location of the narrow band interferers.

An improved antenna and coordination arrangement for use at a base station that will eliminate over the air collisions while doubling the effective data rate of each base station in a network is disclosed. The result will be large area networks which all share exactly the same radio spectrum without mutual interference and little effort required to expand a single base station system to a grid of cooperative base stations forming a coverage area of ubiquitous coverage and multiplied data capacity. Specifically, this disclosure describes an improved antenna arrangement and synchronization system for use when multiple radio base stations, each using a deterministic over the air MAC layer, are located within overlapping coverage areas.

A system and method of damping the ringing response of Band Pass Filters for use in impulse and single cycle modulation systems which are capable of carrying a high data rate and which are severely affected by the ringing response of the Band Pass Filter.

System and method for wave damping

The invention disclosed in this application uses a method of modulation named Integer Cycle Frequency Hopping (ICFH) wherein a carrier signal, comprised of a continuum of sine waves is generated on a single frequency. A data bit representing either a '1' or a '0', depending upon the logic polarity chosen by the builder is imposed upon the carrier signal by modifying the carrier signal at precisely the zero crossing point or the zero degree angle. The method of imposing the data is to cause either a lengthening or shortening of the proceeding 360 degrees of phase angle, thus effectively either raising or lowering the frequency of the carrier signal for just the one, or a succession of cycles at hand. Upon completion of the 360-degree cycle(s), the carrier will return to the original frequency. The main carrier frequency is only modulated beginning at the zero degree phase angle and ending at the 360-degree phase angle. In this modulation scheme as few as one sine wave cycle can be used to represent one data bit. The spectral output of a transmitting device using this modulation scheme will be defined by the difference in frequency between the main carrier signal and the modulating frequency. In the resulting signal a modulated segment of the main carrier frequency can represent either a binary &#x201c;1&#x201d; or a binary &#x201c;0&#x201d;.

Integer cycle frequency hopping modulation for the radio frequency transmission of high speed data

A system and method to transport high bit-rate data over wired or wireless communication systems using specially modulated radio frequency carrier waves using an integer cycle or impulse modulation detection method where the signal to be demodulated is generally split, delayed, inverted and summed. When such integer cycle or impulse modulation modulated signals are passed through the system, the delayed signal is not the inverse of the non-delayed signal when there is data present. The resultant summed signal does not cancel completely, thus, resulting in a demodulated signal that is present only as long as the data is present in the integer or impulse modulated signal. This nulling effect also results in reducing the interference from other signals thereby improving the signal to noise ratio of the system. Thus the system not only reduces the interference from other channels, but it is a very fast demodulator that has the capability of demodulating the signal on an integer cycle basis.

Integer cycle event detection using wavelet pass filter system and method

A method of transmitting and receiving a narrow band integer cycle or impulse modulated signal for spectrum sharing comprising modulating a carrier with a first digital data stream using an integer cycle or impulse modulator then selecting a portion of the sideband of this RF modulated signal for transmission. Next modulating the carrier with a second digital data stream using an integer cycle or impulse modulator and selecting a different portion of the sideband of this second RF modulated signal for transmission. Finally combining and filtering the first and second RF modulated signals to remove all of the first and second RF modulated signals except the selected sideband portions and the carrier which creates a low power signal when transmitted. The transmitted signal is then demodulated through use of a wavelet pass filter which nulls all received RF signals except the low power RF signal when there is digital data present thus allowing for reconstruction of the first and second digital data streams.

Narrow-band integer cycle or impulse modulation spectrum sharing method

An RF signal compression technique used to transport high bit-rate data over wired or wireless means using modulated radio frequency carrier waves whose purpose is to reduce the number of radio carrier modulation events, thus reducing the amount of radio sideband emissions, while increasing the amount of information conveyed by coordinating the modulation events. More specifically an improved compression method with coordinated padding for various methods of modulation by which the spectral channel width occupied by the radio signal and the power spectrum density of said signal can be controlled by numerically adjusting the coding format in a coordinated manner allowing for coordinated modulation events which permits multiple transmissions in a coverage area greatly increasing the amount of information transmitted and available users.

Coordinated numerical control of sideband energy and modulation compression method for the radio frequency transmission of high speed data

The invention disclosed in this application discloses a method for modulating and demodulating compressed binary information that was derived from a binary information stream composed of a binary data sequence of first and second binary states that was modulated onto a carrier which has a waveform with a continuous sequence of wavelets with similar amplitudes defined by a 360 degree cycle between crossover positions representing a substantially zero energy level in which the carrier has been modulated in accordance with said binary data sequence by grouping said wavelets into wavelet groups containing two or more wavelets, receiving said information stream as a binary data sequence of first and second binary states; grouping said binary data sequence of first and second binary states into binary groups of two or more first and second binary states; correlating one of each said wavelets in said wavelet group with one of each possible binary values of each said binary groups, modulating said carrier in accordance with said binary data sequence by altering the amplitude or frequency of the one of each said wavelets in said wavelet groups corresponding to one of each said binary values of said binary groups resulting in a compressed binary modulated carrier, demodulating said compressed binary modulated carrier by detecting the respective amplitudes or frequencies of said wavelets to identify said altered wavelets in said wavelet groups and correlating to said binary values of said binary groups, and reconstructing said binary data sequence from said binary groups resulting in regeneration of said information stream.
