The paper presents an algorithm for the computation of weights in a multi-beam adaptive array. The algorithm is based on the Linearly Constrained Recursive Least Square adaptive filtering of the Constant Modulus signals. It uses real-valued arithmetic and has less computational complexity comparing with the same complex-valued algorithm. A computational procedure of the new algorithm, its complexity estimation and simulation results are also presented. Comparing to the complex-valued algorithm the new one has a smaller transient response and provides in average 2… 4 dB deeper steady-state directional pattern levels towards the interferences.
