自适应均衡(Adaptive Equalization) 是通信系统中一项关键技术,主要用于克服信号在传输信道中因多径效应、频率选择性衰落等因素导致的码间干扰(ISI)问题。其核心在于通过实时动态调整均衡器的参数,自动适应信道特性的变化,从而恢复被失真的信号波形。
动态信道补偿
传统固定均衡器无法应对时变信道(如移动通信中的无线信道)。自适应均衡器通过内置算法(如最小均方误差LMS或递归最小二乘RLS)持续分析接收信号的误差特征(如判决反馈误差),实时更新其抽头系数(Tap Coefficients),形成与当前信道失真特性相反的滤波响应,抵消码间干扰。

Adaptive Equalization(自适应均衡)是通信与信号处理领域中的技术术语,指系统通过动态调整参数来补偿信号在传输过程中因干扰、噪声或信道失真导致的畸变。以下是具体解释:
Adaptive(自适应)
Equalization(均衡)
在无线通信中,若信号因障碍物反射产生多径干扰,接收端的自适应均衡器会实时调整滤波器参数,合并不同路径的信号并消除延迟差异,最终输出清晰的数据流。
