摘要
简单介绍了CPFSK的基本原理,对其调制和解调算法进行了讨论。通过对过零检测、FFT频谱幅值法和非相干解调算法的比较,可以看出采用非相干解调方法具有较好的误码特性。
The basic principle of CPFSK is introduced in this article. The comparison between the detection of zero, the max of frequency spectrum and the algorithm of noncoherent demodulation reveals that the algorithm of noncoherent demodulation is qualified in the probability of errors.
