【Abstract】 In this paper, from the angle of the modern optimal calculation theory, a sub-optimal multiuser detector based on genetic annealing algorithm for solving the hard problem of optimal multiuser detection in Code Division Multiple Access (CDMA) communication system is proposed. The simulation results show that the performance of error bit probability of the proposed method is close to that of optimal multiuser detector and the complexity is much lower.更多还原
