DSE—CMA：一种新的常数模盲均衡算法

针对单输入多输出（SIMO）通信接收系统模型下的常数模算法计算量比较大的缺点，以及另一种改进的CMA算法，即Signed-Error CMA算法收敛性能不确定的弱点，引入了一种新的盲均衡算法，即Dithered Signed-Error CMA(DSE-CMA）算法，并分析了DSE-CMA算法的实现原理和实现过程中的各种约束条件，通过仿真实验比较了这3种算法的性能实验表明，DSE-CMA算法具有与一般恒模算法相近的性能，但计算量明显减小，且比SE-CMA算法稳定。

Dithered Signed-Error CMA: A Novel Constant Modulus Algorithm for Blind Equalization

This paper provided a novel blind equalization algorithm, named dithered signed error CMA algorithm, aiming at avoiding the default of CMA algorithm whose operand is enormous, as well as the default of signed error CMA algorithm whose convergence performance is not robust. Also it gave the realization principle of the dithered signed error CMA algorithm and the respective constrained conditions of this algorithm. At the end, it compared the performance of these three algorithms by simulation. The simulation results show that DSE CMA algorithm has similiar performance to CMA algorithm with reduced computation, moreover, DSE CMA is more robust than SE CMA algorithm.
