摘要： Disclosed is an antenna array system including an antenna array of N≥2 antenna elements that output N antenna signals; an interferer-nulling beam forming network (IN-BFN) coupled to the antenna array, N non-linear filters coupled to the IN-BFN, and a desired signal BFN. The IN-BFN may include N “null BFNs” to generate N null signals, each null BFN applying a respective nulling beam weight set to the N antenna signals to generate a respective one of the N null signals. Each respective nulling beam weight set corresponds to a different respective set of (N−1) independent nulls. Each of the N non-linear filters may filter a respective one of the N null signals to provide a respective one of N filtered signals. The desired signal BFN may apply a desired signal beam weight set to the N filtered signals to generate an output signal.

摘要： A carrier phase correction sub-system for use with a GNSS receiver that utilizes an active null and beam steering controlled radiation pattern antenna (CRPA) determines carrier phase corrections that compensate for antenna phase center movements in the carrier phase measurements taken from the CRPA filtered signal. The carrier phase sub-system utilizes measured radiation patterns, angles of incidence of the satellite signals at the CRPA, and the applied weights to determine carrier phase corrections to be applied to the CRPA filtered signals from which the carrier phase measurements are later taken or to the carrier phase measurements depending on the dynamics of the jamming signal. With the carrier phase corrected, the GNSS receiver may utilize known RTK techniques to resolve carrier cycle ambiguities.

摘要： An antenna apparatus operates as a base station in a wireless network, with a method configuring a transmission beam within such antenna apparatus. The antenna apparatus has a rotatable antenna assembly employing selected transmission beam patterns, and a controller to rotate the antenna assembly altering its azimuth direction. During configuration mode, a sweep operation rotates the antenna assembly to selected azimuth directions. Quality metric determination circuitry determines, for each selected azimuth direction, a link quality metric for wireless terminals based on communication between the wireless terminals and the base station whilst the rotatable antenna assembly is at that selected azimuth direction. Transmission beam determination circuitry determines, from the link quality metrics determined for the wireless terminals at each selected azimuth direction, both a transmission beam pattern and an azimuth direction for subsequent communication with the wireless terminals. The antenna apparatus efficiently self-configures its transmission beam pattern and azimuth direction.

摘要： A method and apparatus for interference suppression in wireless communication systems, especially Orthogonal Frequency Division Multiplexed (OFDM) systems, is presented. The array apparatus includes a two-tier adaptive array system, which provides for both spatial diversity and beamforming at the uplink and includes sub-arrays spaced at a distance sufficient to provide spatial diversity and support beamforming or scanning A Direction of Arrival (DOA) of signals impinging upon the array can be calculated by comparing signals from sub-array elements. Each sub-array can be filtered or beamformed to provide high gain to desired signals received from the DOA (which may be a multipath signal) while simultaneously dampening-out undesired signals, such as co-channel interference (CCI) in the frequency band of operation. The DOA is also used for allocating frequency bins for data signals, such as in an OFDM system, to provide weighted guidelines for bin allocation to maximize received signal power.

摘要： A system and method for scalable processing of a received radio frequency beamform signal is provided. Such a system and methods is useful in conjunction with long range communication between an airborne platform and a surface base station. The scalable system includes a plurality of antenna elements for receiving a directional beam, including a multiplexed data stream, from a base station. A down converter and analog to digital (A-D) converter may then down convert and digitize the multiplexed data stream. A digital splitter may de-multiplex the multiplexed data stream into multiple data streams which are orthogonal to one another. The de-multiplexing may be performed using a fast Fourier transformation on the multiplexed data stream. In these embodiments, the digital splitter divides the multiplexed data stream into frequency groups to de-multiplexing the multiplexed data stream into multiple data streams. The system may also include more than one digital signal processors configured to process the multiple data streams. As the bandwidth of the original multiplexed signal increases, so too can the number of digital signal processors be increased.
