摘要
无线信道盲均衡是近年来通信信号处理领域的研究热点。简要介绍了单用户无线信道盲均衡的数学描述,综述了基于Bussgang技术、高阶统计量、二阶矩、神经网络理论、信息理论盲源分离等几种典型算法,介绍了盲均衡的发展历程、研究现状,最后提出了发展半盲均衡算法及将信息熵理应用于盲均衡算法等有价值的研究方向。
Blind equalization of wireless channel is widely focused on in the field of communication signal processing in the past years. A brief math description of single-user wireless channel blind equalization is provided. Several classical blind equalization algorithms are summarized. The evolution and actuality of blind equalization are introduced. In the end, its possible future development direction is pointed out.
