Radar determination circuitry and radar determination method

Radar device comprising a transmit antenna array comprising a plurality of transmit antennas each having a phase center; and a receive antenna array comprising a plurality of receive antennas each having a phase center, the transmit antennas being arranged such that their phase centers lie on a first straight line, and the receive antennas being arranged such that their phase centers lie on a second straight line; wherein the transmit antenna array and the receive antenna array are positioned relative to each other such that the first straight line and the second straight line extend in an oblique angle relative to each other.

Radar antenna array for three-dimensional imaging

Modulation apparatus, comprising: a first delta-sigma modulator for providing a digital in-phase signal based on a modulation of an in-phase component of a baseband signal; a second delta-sigma modulator for providing a digital quadrature signal based on a modulation of a quadrature component of the baseband signal; a first multiplicative combiner for combining a carrier signal with the digital in-phase signal and for providing an in-phase output signal; a second multiplicative combiner for combining the carrier signal with the digital quadrature signal and for providing a quadrature output signal; a delay component for generating a 90&#xb0; phase shift between the in-phase output signal and the quadrature output signal; and an additive output combiner for combining the in-phase output signal and the quadrature output signal and generating a transmit signal.

Modulation apparatus

A communications system includes a receiver unit connected with a transmission channel. The receiver unit determines a signal power of a first communications signal received over the transmission channel. A transmitter unit is connected with the transmission channel and transmits a second communications signal, wherein a gain of the communications signal being output by the transmitter unit is controllable. A control unit controls the gain of the transmitter unit in response to the determined signal power. At the receiver unit, detection of broadcast signal ingress during data communication is improved and methods for avoiding disturbances between coexisting communications systems may become more reliable. Different distances between successive training symbols suitable for channel estimation may be provided to enhance the noise measurement.

Communications system using adaptive frequency notching

A receiving device according to an embodiment of the present disclosure receives a signal in which a data symbol and invalidation data are arranged. The receiving device includes an amplifying unit that amplifies the input signal and a gain adjusting unit that adjusts gain of the amplifying unit in a section of the invalidation data. The present disclosure can be applied to a receiving device that receives a radio signal of an OFDM system.

Receiving device, receiving method, and non-transitory computer-readable storage medium storing program

To enable processing of a signal at an appropriate level. An analog section in which an acquired signal is processed in an analog fashion and a digital section in which the signal processed in the analog section is digitally processed are included, wherein the analog section includes an adjustment unit that adjusts a gain discretely and the digital section includes a digital step compensation unit that compensates for discrete gain adjustments in the analog section. The digital step compensation unit responds to a transient step in which a gain steeply converts in the analog section and compensates with inverse characteristics of a transient response. The present technology can be applied to an AGC (Automatic Gain Control) system.

Digital filter

A method to perform a cycle synchronization between interconnected sub-networks, in which a reference node connected to one of the sub-networks transmits a respective cycle time information to cycle masters of all other sub-networks at recurring time instants, and the cycle masters of all other sub-networks adjust their cycle time accordingly. An adjustment of the cycle time within a cycle master is performed by determining a first time interval (t, t) in-between two receptions of cycle time information from the reference node with an own clock, determining a second time interval (t, t) in-between two corresponding transmissions of cycle time information from the reference node on basis of the received cycle time information, comparing the first time interval (t, t) and the second time interval (t, t), and adjusting the own cycle length according to the comparison result.

Cycle synchronization between interconnected sub-networks

A method of operating a wireless network, including detecting at least one signal of an external radio source, by a network device of the wireless network, during normal operation of the wireless network, in which while detecting, the network device does not send data to another network device of the wireless network, and changing a communication channel or frequency band, if the at least one signal overlaps with a currently used communication channel or frequency band.
