摘　　要：基于逆矩阵近似算法理论提出了一种新的改进解相关检测器,与标准的解相关检测器相比,改进解相关检测器具有实现复杂度低、同时误比特率和抗“远-近”效应性能影响很小的特点,通过大量的仿真实验,结果证明了改进算法的可行性。Based on the theory of matrix inverse approximate computations new amendatory decorrelating multiuser detection is provided. Comparing with the normal detection, this detection provide a lower complexity and its influence on bit-error probability and near-far effects can be very little. From a lot of simulated experiment, the result proved the algorithmic feasibility.
