Abstract

Adaptive beamforming is based on the RLS (recursive least squares) algorithm realized by the RLS systolic array (RLSSA) proposed by McWhirter in 1983. The authors use CORDIC (CO-ordinate Rotation Digital Computer) algorithm to implement RLSSA. Only shifting and adding operations are employed to realize all the primitive array´s complex procedure. The authors have specially designed some proposed logic and circuits. After all levels simulation, the layouts based on CMOS 1.2 um technology. The system can reach 2 Mhz sampling rate with robust performance
