A robust adaptive beamforming algorithm based on least square constant modulus algorithm (LSCMA) is proposed in this paper. The CMA adaptive array was designed to lock onto the desired signal having the constant modulus property. The proposed algorithm employs both the DOA information as well as the constant modulus property of the signals. This enables the beamformer to avoid self-cancellation caused...
The convergence rate of the power inversion (PI) algorithm utilized in null steering antenna is of vital importance to handle interferences in efficient way. This paper presents the in-depth analysis of the factors affecting the convergence rate of null steering antenna utilizing power inversion algorithm. Apart from choosing optimum value of step size, factors like number of snapshots, signal structure,...
Smart antennas are the key technology to suppress interferences and enhance the desired signal in strong interfering environment for satellites and GPS Signals. Smart/Adaptive arrays uses certain algorithms to process the incoming signal. A systematic comparison of the performance of different Adaptive Algorithms for beamforming for Smart Antenna System has been extensively studied in this research...
