中文摘要：
基于Cholesky分解，给出了用户幅度估计的迭代公式，从而获得用户功率排序．在解相关判决反馈检测器中，通过置换矩阵实现了用户判决次序按照功率递减顺序排列，使最强用户最先得到判决．性能分析表明，判决排序改善了检测器的误码性能．仿真结果与理论预测一致，判决排序均衡了系统的误码性能，使越弱信号用户的误码性能改善越大．
英文摘要：
An iterative formula of the amplitude estimate is presented based on Cholesky decomposition for the signal power order. The decision arrangement in the order of decreasing amplitude is implemented by permutation matrix in decorrelating decision-feedback multiuser detector, it will make the strongest user get a very first decision. Performance analysis shows that the decision arrangement can improve the bit error rate （BER） performance of the detector. The simulation results accord with the-oretical prediction which summarizes that the decision arrangement will enhance the BER performance of the weaker user and equalize that of the whole system.
