解釋
自動頻率控制迴路-
2. as for the intermediate frequency part in integrated circuits ( ic ' s ), we introduce feedback automatic gain control ( agc ) loop in view of its fargoing dynamic range and convenient precision adjustment, hence stable power of fore - demodulator signal and maximum systematic gain are ensured
2 、中頻部分採用集成電路的反饋式自動增益放大環路,動態控制范圍大,控制精度調節簡便,是系統增益的最大來源,同時也保證了中頻解調器前信號的功率穩定。 -
The algorithm of cross product automatic frequency control ( cpafc ) and frequency bin technology is used for tracking larger frequency deviation. the paper gives out a scheme of digitized carrier synchronization loop, in which the digitized costas loop is used as a basic part while cpafc and frequency bin technology as auxiliary
在此基礎上提出了數字化、軟體化的載波同步環路演算法方案,主要採用數字化科斯塔斯環的形式,並加以自動頻率跟蹤演算法和頻率開槽技術的輔助來實現載波同步。
