Abstract :
Low-complexity adaptive receivers based on smart antennas with post- and pre-despreading structures are presented. Comparisons between three space-time (ST) schemes employing minimum-mean-square-error, a constant modulus algorithm, and a decision-directed algorithm for constant modulus signals are investigated in detail
