摘要

一种能够进行可变波特率(f/sub / b/)操作的解调器满足了卫星通信系统(如VSAT系统)的前向纠错解码器的要求。一种新的频率采集方法，称为扫频自动频率控制，具有宽的f/sub / b独立采集范围，并防止载波恢复电路的误锁定。作者已经对这种解调器进行了评估，并确认其性能令人满意。

A digital signal processing demodulator with a wide frequency acquisition range

A demodulator capable of variable baud rate (f/sub b/) operation satisfies the requirements for a forward error correcting decoder for satellite communication systems such as VSAT systems. A new method of frequency acquisition, called swept automatic frequency control has a wide f/sub b/-independent acquisition range and prevents false locking of the carrier recovery circuit. The authors have evaluated such a demodulator and confirm that it performs satisfactorily.<>
