摘　　要：针对确定性的短码，采用一种简化算法，计算复杂性低，结构简单，从而避免了对方程的求逆运算．仿真结果表明其性能优于解相关检测器和最小均方（ＭＭＳＥ）检测器．A simplified algorithm is proposed in a short coding subsystem in order for avoiding the inverse operation of the equation and reducing its complexity, which simplifies the configuration of a multi-user detector. By simulations, it is shown that the performance of this detector is much better than those of the decorreleating detector and MMSE detector.
