| 摘 要： | 介绍了一种适合于突发模式下的PSK信号遥控副载波解调方法,其目的是对于突发副载波信号接收时实现快速可靠的捕获,并进行载波同步和位定时同步。文中设计的解调器是有别于传统解调器的全数字接收解调器,利用软件无线电的思想用软件方法实现解调,介绍的Viterbi载波同步算法和Gardner位定时同步算法结构简单,易于利用数字硬件实现,仿真结果也验证了此解调算法的可行性和有效性。

| Abstract: | This paper proposes, a demodulation method suitable for burst PSK remote sub-carrier signal. This demodulation method is designed to quickly and effectively accomplish carrier synchronization and bit synchronization. This synchronization, based on software wireless theory, is achieved by using software. The Viterbi carrier synchronization and the Gardner bit synchronization mentioned in this paper are very simple in configuration and easy in digital hardware implementation. The simulation results indicate that this demodulation method is feasible and effective. |
