Abstract

A downlink “feedback” channel for an algorithm of LTE Femtocell Inter-cell Interference mitigation is designed in this paper. Specifically, in the receiver, a blind-detection method is established in order to correctly decode the signal transmitted. The simulation result shows that the designed channel would have low block error ratio (BLER). A simulation was implemented on DSP, and results also show that the designed downlink “feedback” channel is effective as the inter-cell interference (ICI) mitigation algorithm.
