摘要
本文阐述了恒模算法的数学模型和基本原理,对近年来出现的各种恒模算法进行了综述,简要分析了这些算法的工作原理和收敛特性。在此基础上讨论了恒模算法在盲均衡、盲多用户检测、干扰抑制和盲波束形成等领域的应用。最后对恒模算法的发展趋势进行了展望。
The mathematics model and basic principle of Constant Modulus Algorithm (CMA) are shown firstly, then several CMAs proposed recently and its principle and convergence behavior are reviewed systematically. Finally applications of CMA are discussed in blind equalization, blind multiuser detection, interference suppression and blind beamforming, and have a view on the development tendency to CMA.
