T/4相干累积分数间隔多模盲均衡算法
T/4 coherent integration fractionally spaced multi-modulus blind equalization algorithm
摘要
Abstract
Aiming at the problem of convergence difficulty and the big residue Mean Square Error (MSE) existed in high-order QAM signal equalization, this paper proposes the Coherent Integration based T/4 Fractionally Spaced Multi-Modulus blind equalization Algorithm (CIFSMMA) on the basis of analyzing the Multi-Modulus blind equalization Algorithm (MMA), T/4 Fractionally Spaced Multi-Modulus blind equalization Algorithm (FSMMA) and coherent integration algorithm. The underwater acoustic channel simulation results with 128QAM signal show that the convergence speed of the proposed algorithm is faster, the steady-state error is smaller and the eye pattern is more clear.关键词
