| 摘 要： | 基于上行干扰抑制合并技术（IRC）提出了两种干扰检测算法。第一种改进方案需要预先知道目标小区和干扰小区信道状态信息，第二种改进方案在不知道目标小区和干扰小区信道状态信息的情况下，通过盲估的方法进行计算。这两种算法都能有效抵御同频干扰，并减少误码率。

| Abstract: | LTE system with same frequency interference is one of the problems which need to be solved in base station and termi- nal. In order to solve the problem of same frequency interference in LTE system, two schemes are proposed for interference detection based on interference rejection combining （IRC）. The first scheme needs to know in advance the channel state information of target cell and interference cell. The second scheme is in the case of without knowing the channel state information of target cell and interference cell, and calculated by the method of blind estimation. These two algorithms can effectively resist the same frequency interference and reduce the bit error rate. |
