自適應均衡(Adaptive Equalization) 是通信系統中一項關鍵技術,主要用于克服信號在傳輸信道中因多徑效應、頻率選擇性衰落等因素導緻的碼間幹擾(ISI)問題。其核心在于通過實時動态調整均衡器的參數,自動適應信道特性的變化,從而恢複被失真的信號波形。
動态信道補償
傳統固定均衡器無法應對時變信道(如移動通信中的無線信道)。自適應均衡器通過内置算法(如最小均方誤差LMS或遞歸最小二乘RLS)持續分析接收信號的誤差特征(如判決反饋誤差),實時更新其抽頭系數(Tap Coefficients),形成與當前信道失真特性相反的濾波響應,抵消碼間幹擾。

Adaptive Equalization(自適應均衡)是通信與信號處理領域中的技術術語,指系統通過動态調整參數來補償信號在傳輸過程中因幹擾、噪聲或信道失真導緻的畸變。以下是具體解釋:
Adaptive(自適應)
Equalization(均衡)
在無線通信中,若信號因障礙物反射産生多徑幹擾,接收端的自適應均衡器會實時調整濾波器參數,合并不同路徑的信號并消除延遲差異,最終輸出清晰的數據流。
