摘要

针对正交频分复用（OFDM）系统中射频前端失真—同相/正交（IQ）不平衡影响系统性能的问题，提出了一种新型的IQ不平衡频域估计与补偿算法。通过同一个子载波上的两个不同导频信号，抵消信道的影响，以减小算法复杂度，便于实现。仿真结果表明，该算法既极大地降低了计算量，又取得了较好的估计与补偿性能，性能优于传统的算法。

Abstract

To solve the problem of deterioration of system performance for the RF front-end distortion and IQ imbalance in orthogonal frequency division multiplexing（OFDM）system，a novel IQ imbalance frequency domain estimation and compensation algorithm was proposed.The effect of channel could be offset，the complexity of algorithm could be reduced and the implemention conld be achieved easily using two different pilot signals on one sub-carrier.The simulation results show that the algorithm not only greatly reduces the computational complexity，but also gets a better estimation and compensation performance，and the performance is better than traditional algorithms.
