摘要
通过对信号进行基于瞬时自相关的瞬时频率提取的方法对中频信号进行分析、识别,然后可以在FP-GA内部构造一个多通道匹配滤波器对信号进行匹配。然后对多通道匹配滤波进行仿真。仿真结果表明,可以从多通道匹配滤波中判断匹配的正确与否,从而可以实现信号的分选。
The article analyses the signal through the method of gaining instant frequency on the base of mstant correlation. then we can make up a multicenter matching filter in the FPGA. Then we emulate the multicenter matching filter. The emulate result indicates that we can estimate the correctness of the multicenter matching filter, and we can sort the ,signal correctly.
