| 中文摘要:多用户检测技术是第三代移动通信系统关键技术之一。其主要思想是充分利用所有用户的信息对接收信号做联合检测，抑制多址干扰，缓解“远-近”效应，从而有效地提高系统容量。本文对多用户检测技术进行初步的研究，尤其是两种主要的线性多用户检测技术：解相关检测和最小均方误差检测，做仔细地研究和比较，并用MATLAB在AWGN信道下和DS-CDMA系统中做仿真。 |

| The Study of Decorrelation Detection and MMSE Detection in Multi-user Detection |

| Abstract:Multi-user detection is one of the most important key technologies in 3rd generation mobile communication. The main idea is to make full use of the information for all users to do the joint detection of received signal,control the multiple access interference and ease the “near-far” effect so as to improve the system capacity effectively. This paper studies the technology of multi-user detection, especially two main linear multi-user detections: decorrelation detection and MMSE detection, and it compares these two detectiony systems. Finally, it works out simulation results under DS-CDMA system in AWGN channel. |
