摘　　要：对于处于小区边缘的用户,尤其是密集城区的小区边缘用户,会受到较大较多的邻小区用户的同频干扰,信干比较低,为了提升上行业务吞吐量,研究MRC和IRC两种自适应抑制算法可有效改善性能。通过研究和两种算法测试结果分析可得,IRC算法在有较大干扰情况下优于MRC算法,如果干扰较大,选择IRC算法;如果干扰较小,选择MRC算法,两种算法在不同干扰以及不同信噪比时性能不同。For the users at the edge of the cell, especially those in the dense urban area, they will be subject to the same frequency interference of more neighboring cell users, and the SIR is relatively low. In order to improve the upstream traffic throughput, two adaptive suppression algorithms, MRC and IRC, can effectively improve the performance. Through the research and analysis of the test results of the two algorithms, it can be concluded that IRC algorithm is better than MRC algorithm in the case of large interference. If the interference is large, IRC algorithm is chosen;if the interference is small, MRC algorithm is chosen. The performance of the two algorithms is different in different interference and different signal-tonoise ratio.
