摘　　要：分析可用于或已经用于长期演进(LTE)无线通信系统的小区间干扰抑制技术.探讨解决潜在信号与干扰加噪声比覆盖中断问题的技术,包括功率控制技术、空分多址接入天线技术、干扰消除技术和译码技术等.研究认为,干扰消除能带来显著的增益,但由于处理的复杂性,仅应用于LTE上行链路中,并且还需要基站间毫秒级实时交换信息以实现LTE系统的最大增益;球面译码和脏纸编码等译码技术能提供的相当好的增益,但处理复杂度限制了其在UL链路上的应用;功率控制技术和多入多出(MIMO)技术是基于基站间的技术,具有潜在的性能增益和基站实现的可行性.The analysis of being used or have been used for long term evolution（LTE） wireless communication systems Inter-cell interference suppression has been put forwarded.The problem of the interruption coverage in potential signal to interference plus noise ratio was investigated.Including power control technology,space division multiple access antenna techniques,interference cancellation techniques and decoding technology,etc..The research suggest that interference cancellation can bring a significant gain,but because its complexity to dealing with,it′s only applied to LTE uplink,and the base stations also need real-time exchange of information between the millisecond LTE system in order to achieve maximum gain;spherical coding and dirty paper coding decoding technology can provide fairly good gain,but the complexity for dealing limit the UL link applications;power control technology and multiple input multiple output（MIMO） technology is base on the inter-base station technology with the potential performance gain and the feasibility of achievement on base stations.
