| 摘 要： | 在加权多模盲均衡算法的基础上,提出了一种误差函数在判决引导模式和加权多模模式之间切换的改进算法。算法根据误差函数符号的比较结果,在判决引导模式与固定加权多模模式之间切换,可充分利用两种模式的优点,更好的匹配信号星座,避免动态权值多模算法中权值的调整。仿真结果表明与动态权值多模算法相比,改进算法可获得更快的收敛速度和更低的稳态均方误差,计算量增加较少,适用于QAM信号。 |
| 关 键 词： | 盲均衡 判决引导 加权多模 收敛速度 稳态均方误差 |

| Abstract: | An improved algorithm in which the error function was switched between decision directed mode and weighted multimodulus mode was proposed based on the weighted multimodulus blind equalization algorithm.The proposed algorithm switches between decision directed mode and fixed weighted multimodulus mode according to the comparison of the signs of error functions,which can utilize the benefits of the two modes to achieve better constellation-matching performance and avoid the weight adjustment in dynamic weight... |
| Keywords: | blind equalization decision directed weighted multimodulus convergence rate steady state mean square error |
