| 摘 要： | 介绍了调幅、调频的解调算法，对比了相干解调和非相干解调算法，并在相干解调算法的基础上，提出了正交解调算法和正切解调算法。利用LabVIEW数据流图的编程方式，编程得到二次正交解调算法，实现复合调制信号的数字化解调。通过仿真与实验结果可以得知，采用二次正交解调算法对复合调制信号进行数字解调能够得到较好的解调效果。

| Abstract: | Focusing on the two issues of the algorithm for complex modulation signal's demodulation and the software implementation,this paper introduces the demodulation algorithm for amplitude and frequency modulation,compares the coherent demodulation algorithm with non-coherent and proposes the quadrature demodulation algorithm and the tangent demodulation algorithm based on the coherent demodulation algorithm.Using the data flow diagram programming of LabVIEW, this paper implements the second quadrature demodulat... |
