摘　　要：针对LTE通信协议小区间干扰抑制技术,设计了一条完整的下行反馈信道。其中,在接收端的仿真中采用了一种盲检测技术。仿真与之后的DSP实现证明,这种盲检测技术能够正确解码发送端传输的信道,可以得到非常低的误码率和误块率。A downlink ＂feedback＂ channel for implementing an algorithm of LTE femtocell inter- cell interference mitigation is designed in this paper. Specifically, in the simulation of receiving end, a blind -detection method is developed in order to correctly decode the signals transmitted. It is shown that the designed channel can yield a low block error ratio and the designed downlink ＂feedback＂ channel is effective in applying the inter-cell interference mitigation algorithm. Simulations are implemented using the proposed DSP techniques.
