This paper demonstrates the effectiveness of local search algorithm (LS) for multiuser detection (MuD) in multiple access DS/CDMA communication networks, using digital sinal processing platform. Even been the simplest search algorithm found in literature, the 1-LS algorithm applied to MuD problem is capable to achieve good performance-complexity tradeoff, indicating a certain efficiency in approaching the optimal solution (NP complete problem) under severe operation system and channel conditions, i.e., flat Rayleigh channel, medium and high system loading and a wide range for signal-noise ratio.
