摘要

随着无线通信频段的不断提高,非理想载波所引入的相位噪声对多输入多输出正交频分复用(MIMO-OFDM)系统性能的影响也越来越突出,不仅影响OFDM系统载波的正交性,同时导致多天线预编码性能急剧下降。相位噪声对MIMO-OFDM系统的影响可分为公共相位误差(CPE)和载波间干扰(ICI)两部分。本文对CPE影响MIMO-OFDM系统的性能进行深入分析,提出一系列基于频域正交导频设计的CPE估计算法,以实现对CPE的有效抑制;最后,在多个场景下进行链路仿真,充分验证了提出算法的有效性和可靠性。

Abstract

With the actually used frequency band going higher and higher in wireless communications, the influence of phase noise induced by imperfect carrier on Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing(MIMO-OFDM) systems are becoming increasingly acute. This results in not only the destruction of the orthogonality of OFDM system carriers, but also the multiple-antenna precoding performance degradation. The influence of phase noise on MIMO-OFDM systems are composed of Common Phase Error(CPE) and Inter-Carrier Interference(ICI). In this paper, it is first analyzed that how CPE influences the performance of a MIMO-OFDM system, after which a series of novel CPE estimation algorithms are proposed based on frequency domain orthogonal pilot design; finally the validity and reliability of the algorithms are verified by system link simulation under various wireless transmission scenarios.
