基于恒模准则的半定松弛盲均衡
Semidefinite Relaxation Based Blind Equalization using Constant Modulus Criterion
摘要：
盲均衡是一个经典而又开放的问题。基于统计的算法，如恒模（CM），得到了广泛的研究。盲算法的一个固有问题是均衡信号的相位模糊。在这篇文章中，我们提出了一种新的方案，基于CM准则，并利用一类LDPC码的非对称性来解决相位模糊。具体而言，提出了一种新的配方与修改CM目标函数和放松代码约束。
英文摘要：
Blind equalization is a classic yet open problem. Statistic-based algorithms, such as constant modulus (CM), were widely investigated. One inherent issue with blind algorithms is the phase ambiguity of equalized signals. In this letter, we propose a novel scheme based on CM criterion and take advantage of the asymmetric property in a class of LDPC codes to resolve the phase ambiguity. Specifically, a new formulation with modified CM objective function and relaxed code constraints is presented.
