摘　　要：从误码率、频率利用率以及吞吐量等性能指标出发,分析比较了正交频分多址接入(OFD-MA)系统干扰抑制方式以及相关技术,并由此给出这些技术在降低误码率、提高频率利用率和吞吐量等性能方面的优点与不足。分析了未来移动通信系统中同频干扰抑制技术发展的若干问题,为分析抑制同频干扰打下了基础。Starting with the performances such as error rate, frequency utilization and throughput, this paper analyses and compares the suppressing interference methods and related technologies for OFDMA（Orthogonal Frequency Divided Multiple Access） systems, as well as advantages and disadvantages of performance of these technologies in reducing error rate and improving frequency utilization and throughout, etc. Meanwhile, it analyses those problems concerning the development of co- channel imerference（CCI） suppression technology in future mobile communication systems, which provides the foundation for further research on CCI suppression technology
