基于Goetzel算法的8FSK信号调制解调的实现

Realization of modulation and demodulation of 8FSK based on the Goetzel algorithm

实现了短波通信自动链路建立(ALE)系统中8FSK信号的调制解调,其中所采用的Goetzel算法解决了码元同步问题,同时降低了算法复杂度和计算量,加快了解调速度。

This paper introduces a method for the modulation and demodulation of 8FSK in the ALE system. The method adopts the Goetzel algorithm to get synchronization and reduce the complexity of demodulation.
