Abstract :
We extend the results from Wang and Dowling (see. Proc. ICASSP, Atlanta, GA, p.2678-81, 1996) to provide a low-cost and high-performance blind adaptive interference suppression scheme for CDMA systems. Simulation results confirm that the proposed algorithm outperforms several existing algorithms, even under the most severe cases of near-far and multipath conditions
