  1. It is necessary in digital communication system that carrier recovery can compensate frequency offset and phase jitter brought by transmission and modulation. this paper is mainly focused on carrier recovery technique. we introduce the channel model at cable headed and receiving site. firstly, we introduce the principle of carrier recovery and give some algorithms of them, which are directed - decision, reduced constellation and frequency sweeping

    本論文緊緊圍繞著數字通信系統中的載波恢復技術,在介紹了有線通信系統所用的調制解調通道模型后,首先闡述了載波恢復技術的思想和基本原理,在此基礎上給出了三種載波恢復演算法,即判決導向演算法、簡化星座判決演算法和掃頻演算法,並且給出了其各自的模擬圖:然後深入研究了一種適合高階qam並且能糾正較大頻偏的載波恢復技術:極性判決演算法。
