Abstract
This paper proposes an initialization scheme for a constant modulus algorithm (CMA). The technique can significantly improve convergence properties of CMA, which is employed for weight adjustment of an adaptive antenna system. The technique exploits a beam of a switched-beam element phased array antenna with the maximum received power to initial CMA. In addition, a main beam of the antenna can be switched into more directions by utilizing four one-bit phase shifters. Antenna patterns are shown and selected for CMA initialization. Simulation results are shown to evaluate SINR performance of the proposed technique
