| Abstract: | According to the principle of FM signal demodulation in base band,mini-angle approximate demodulation algorithm is improved to get better adaptability in AWGN channel.And the validity and correctness of the method is proved by means of theoretical analysis,formula derivation and simulation of MATLAB.On this basis,FPGA programming is completed and validated in practical engineering.Experimental results demonstrate the viability of that method. |
