A Comprehensive Survey on Antenna Array Signal Processing*

Using any surface to realize a new paradigm for wireless communications

“…LAE can be manufactured using conductive ink-based printing methods on flexible and transparent polymer films, incorporating simple digital switches such as polymer diodes [9]. On the other hand, alternatives such as antenna arrays [8] require transceivers with accurate state control and real-time signal processing capabilities, posing scalability considerations in terms of size, power and manufacturing cost.…”

Directivity Gain Improvement in Phase Array Antenna via a Novel L2-Norm Adaptive Beamforming Algorithm

“…An adaptive beam-former can adjust its weight automatically according to the given criteria. However, beam-former"s performance highly degrades in case of array imperfectionalities such as time delay error, steering direction error, multipath propagation effects, phase errors of the sensors and wave front distortions [16][17][18][19][20]. An optimal beamforming at either/both end of communication system results in enhanced received power, relatively lower bit error rate (BER) and higher signal to noise plus interference ratio (SNIR).…”

A Novel Adaptive Algorithm Addresses Potential Problems of Blind Algorithm

“…In this paper, the effectiveness of a hybrid algorithm called CMLMS algorithm is proposed in order to evade the use of potential problems existing with CMA algorithm regarding its convergence [13][14][15][16][17][18][19]. Its performance is evaluated in an adaptive linear array having multiple inputs including the presence of a cochannel interfering signal, AWGN of zero mean and Rayleigh fading channel.…”
