摘要:

本文提出了软件妆收机中抑制载波双边带调幅（DSB-SC）信号载波同步的一种算法，根据下变频后的基带信号估计出收发载波的频差，并经卡尔曼滤波后结合数字锁相环以达到载波捕获范围宽、跟踪速度快、环路噪声小的特点。文章最后给出了一个具体实例的仿真结果。

An Algorithm for Carrier Synchronization of DSB-SC Signal in Software Receivers

()

Abstract:

This paper presents an algorithm for carrier synchronization of DSB-SC(amplitude modulation, double sideband suppressed carrier) signal in software receivers. The frequency deviation detector processes the baseband signal and calculates the frequency deviation which is filtered by Kalman filter,and then combining frequency deviation estimation with DPLL(digital phase-locked loop ) yields a larger pull-in range,shorter acquisition time and smaller noise bandwidth. Finally,an example and its simulation results are presented.
