摘要 提出了一种新的无线信道多用户检测算法。采用最小均方准则作为常模算法的约束条件,以保证该算法代价函数的最优点能落在约束空间中。仿真结果显示该算法优于现有典型的约束优化算法。 A new algorithm is proposed for multi-user detection in wireless communication channel. Based on the Minimum-Mean-Square-Error(MMSE) criterion, the cost function of the constant modulus algorithm will be located in the constrained searching space. Computer simulations show the efficiency of the proposed algorithm.
