基于QPSO的小波分数间隔盲均衡算法
Wavelet Fractionally Spaced Blind Equalization AlgorithmBased on QPSO
摘要
Abstract
This paper proposes an orthogonal wavelet transform fractionally spaced constant modulus blind equalization algorithm based on the optimization of Quantum Particle Swarm Optimization(QPSO). It analyzes of the futures of the quantum-behaved particle swarm optimization algorithm and orthogonal wavelet transform. The algorithm can reduce the autocorrelation of the input signals, and the equalizer weight vector can be optimized by QPSO algorithm with the characteristics of high searching ability, rapid convergence and high robustness. Simulation result shows that this algorithm can reduce steady mean square error, improve convergence rate and no distortion transmission performance of signal in underwater acoustic channels.关键词
