基于特征参数的数字信号识别

Digital Signal Identification Based on Parameter Statistic Method

基于Y.T.Chan的理论,分析了信号特征参数R.计算机仿真结果说明:利用该特征参数可以区分不同的数字幅度调制信号,如果与其他的参数相结合就能够实现和完成对所有数字信号的识别,因此基于参数统计法来实现调制信号的识别是可行的和有效的,适用于多模式调制解调技术.

That paper analyzes a new signal feature parameter-R based on the Y.T.Chan＇s theories,and the result of computer simulation demonstrates that the feature parameter can classify different digital amplitude modulation signals,and if combining it with other parameters and then it can realize and complete identifying all digital signals.Therefore the digital signal identification based on parameter statistic method is effective and feasible,and can be used for the technique of multi-mode modem.
