Modified Implementations of RLS Digital Beamformer
2005 IEEE Antennas and Propagation Society International Symposium, 2005Some modifications of the conventional recursive least square (RLS) beamformer are presented. The proposed modifications allow us both to reduce the computational complexity of RLS beamformer and to increase its numerical performance. The proposed modifications are based upon the application of vector operations instead of matrix operations and ...

Data-Based Model for Wide Nulling Problem in Adaptive Digital Beamforming Antenna Array
IEEE Antennas and Wireless Propagation Letters, 2019An adaptive digital beamforming (DBF) array is vital in advanced wireless systems. Beamforming problems in DBF arrays could be time-consuming and inflexible, as most of them are only solvable by optimization algorithms.

A C-band digital beamforming array
1988 IEEE AP-S. International Symposium, Antennas and Propagation, 2003A 32-element C-band digital beamforming (DBF) array which serves as a testbed for algorithm development and demonstration of digital beamforming technology is presented. Cost reduction, primarily in the areas of receiver modules, I/Q generation, and array alignment/calibration, was an overall consideration.

Digital Interpolation Beamforming for bandpass signals
The Journal of the Acoustical Society of America, 1978Digital time domain beamforming requires that the output of each hydrophone be sampled prior to beamforming at a rate consistent with the Nyquist criterion for waveform reconstruction. If the sample rate is insufficient for direct realization of the required beam delays, then the desired delays can be achieved by digital interpolation at either the ...
