摘要

In order to defeat both intersymbol and multiple accessninterference arising in code division multiple access systems, numerousnmultiuser detection techniques have been investigated . Actually, thencomputational complexity of the optimum maximum-likelihood multiuserndetector (MLMD) increases exponentially with the number of users,ntherefore it is infeasible. We propose two suboptimum versions of MLMD,nespecially designed for down-link connections, which are based on ancomputational efficient reduced-state technique. It has been found thatnthese algorithms have a significant performance gain as compared withnother suboptimum joint detection criteria, such as zero forcing andnminimum mean squared error. Moreover, they have a computationalncomplexity which is proportional to the number of users
