恒模算法与子空间法相结合的分数间隔盲均衡

The Constant Modulus Algorithm and Subspace Approach for Blind Fractionally Spaced Equalization

恒模算法和子空间法是目前广泛应用于通信信号处理中的两种盲算法。将恒模算法和子空间方法相结合,提出一种基于恒模算法与子空间分解法的分数间隔盲均衡算法,仿真结果表明,新算法的收敛特性明显优于传统的恒模算法。

The constant modulus algorithm (CMA) and subspace approach are both blind algorithms, which are applied in the communication signal processing widely. We combine the CMA with the subspace approach and propose the CM_SUB blind equalization algorithm. Simulation results show that the proposed CM_SUB algorithm is superior to the traditional CMA algorithm on convergence rate.
