摘要 通过对CDMA通信系统性能的分析,结合一种有效的近似算法把盲多用户检测问题转化为一个具有约束条件的二次规划问题,给出了一种改进的CDMA盲自适应多用户检测算法,仿真实验结果表明,在复杂的时变信道中,该算法比其他算法具有较强的抗多址干扰能力和较快的收敛速度。 By analyzing the performance of CDMA system, combining a efficient approximate algorithm, the blind multiuser detection problem is translated to a quadratic programming problem with some constraints, an improved blind adaptive multiuser detection algorithm of CDMA system is proposed, the simulation results show the proposed algorithm possesses stronger capability of anti-MAI and faster speed of convergence in complex time-varying channel.
