二进制移频键控的调制及软件实现

The software comes true and mingle of binary frequency shift key

在研究2FSK信号调制及解调过程的基础上,提出了一种新的基于迟延的非相干解调算法,并对算法具体实现和使用进行了详细的说明,最后分析了所用算法和该算法的VC++.NET软件实现过程.

This paper introduces the demodulation technologies of 2FSK signal, and gives a kind of timely demodulation system of 2FSK signal,using computer as hardware,of which the demodulation algorithm is improved on difference demodulation. The character and demodulation algorithms in common use are analyzed, then the signalization and FIR filter are studied, finally we particularly analyse the demodulation algorithm used in this paper and its realization using VC ＋ ＋.
