Results show that with some extra power, the multi-rate ICI self-cancellation scheme can be effectively used in OFDM systems to combat phase noise problems. 在分析和模拟中可以发现，当环境具有载波频率漂移或相位杂讯下，只要能多提供一些传输能量，多重码率子载波间干扰相消法便可有效地达到较高的频谱效率。
Based on the assumption, the proposed method solves the linear channel parameters of each path and creates a channel matrix which can be used for ICI cancellation. 基于这个假设，我们解出线性的通道参数进而重建通道矩阵，目的去消除载波间的互相干扰。
