摘要：

In this letter, we introduce the interference suppression in direct-sequence code-division multiple-access systems using the minimum-mean-square-error criterion based on a block adaptive filtering algorithm. Simulation results show that the proposed implementations of the block algorithm requires much lower computation as compared to recursive least square (RLS) algorithms while maintaining comparable convergence characteristics as that of the RLS algorithm. Also, the block algorithm is shown to be near-far resistant. It is concluded that the proposed implementation is suitable for moderate block sizes, which will have fast convergence while introducing small processing delay.
