  • This paper presents a sub-optimal data-selected scheme based on chip-matched filter for the multi-user receiver in multi-path CDMA channels, and studies the impact of this scheme on Multiple-Access Interference (MAI) and Inter-Symbol Interference (ISI). Then, the Recursive Least-Square (RLS) blind space-time multi-user detection based on the constrained condition is presented. Finally, the results of the simulations illustrate that the presented method is effective.
