The present invention provides systems and methods relating to ultra-wide band communications. A method is provided for transmitting information using ultra-wide band transmission. The method includes allocating, for signal transmission, each of a plurality of frequency sub-bands. The method further includes sending an ultra-wide band transmission comprising the information by transmitting a burst symbol cycle signal over each of the plurality of frequency sub-bands.

System and method for multi-band ultra-wide band signal generators

The present invention provides multi-band ultra-wide band (UWB) communication methods and systems capable of adaptively and scalably supporting different applications with different requirements, as well as different desired or ideal properties relating to the communications. A method is provided for transmitting information using multi-band ultra-wide band transmission, including transmitting a signal over each of multiple frequency sub-bands, and allowing variation of at least one transmission parameter to facilitate trade-off between at least two of power consumption, energy collection, bit rate, performance, range, resistance to multiple access interference, and resistance to multipath interference and spectral flatness.

Scalable ultra-wide band communication system

The present invention provides ultra-wide band communication systems and methods, including multi-band ultra-wide band communication systems and methods. Methods and systems are provided in which frequency sub-bands of an ultra-wide band spectrum are allocated for signal transmission. An ultra-wide band transmission including the information is sent, including sending a signal over each of the plurality of sub-bands. Methods are further provided in which a first data signal containing information is converted into an encoded signal using an Inverse Fast Fourier Transform. The encoded signal is converted into an encoded ultra-wide band signal that can be pulsed or transmitted using burst symbol cycles. The encoded pulsed ultra-wide band signal is decoded using a Fast Fourier Transform to obtain the information.

Multi-band ultra-wide band communication method and system

A method and apparatus for determining the timing of symbols within a multiple symbol telecommunicated message by evaluating signal characteristics in both the preamble and data portions of a message. Samples of a received signal are taken at a periodic basis and a predetermined characteristic of the signal is evaluated for each sample. The sum of every ith sample may be evaluated to determine the symbol framing within the message.

Method and apparatus for determining symbol timing in a wireless

A method and apparatus for reducing power consumed by mobile wireless units, such as personal communications systems or wireless PBX telephones, by reducing the frequency with which various circuits within the units are fully energized. During on-going voice communications between a base station and a wireless unit, the wireless unit reduces the frequency of its references to a control channel and may eliminate such references altogether. In addition, while idle, the wireless units may not attempt to reference the control channel during all occurrences of the control channel, reducing both power consumption and the possibility of collisions with other wireless units in attempting to access the control channel.
