摘要 为改善α稳定分布噪声中非线性多径衰落信道均衡器的性能,提出一种α稳定分布噪声中非线性信道均衡算法。该算法针对α稳定分布噪声中的非线性多径信道,在传统空间分集技术的基础上引入核最小平均p范数算法。仿真实验结果表明,新算法的性能与多个接收机中均衡效果较好的均衡器保持一致,避免单个接收机接收时,由于其对应的信道质量太差而导致最终均衡效果不能满足实际需求的情况。 In order to improve the performance of nonlinear multipath fading channel equalization inαstable noise,the paper proposes a nonlinear multipath channel equalization algorithm inαstable noise based on space diversity technology.The algorithm brings in kernel least mean p norm(KLMP)algorithm on the basis of traditional space diversity technology.Simulation results show that the new algorithm can be consistent with the equalizer of better performance,avoiding the situation that the final equalization result can’t meet actual demand due to its poor channel quality when there is only one receiver.
