4FSK调制解调的matlab代码。采用相干解调的方式4FSK进行解调，与大多数方案的包络检波不同。基带信号用四种电平来表示，与调制信号相区分。(Demodulation matlab code 4FSK modulation. Coherent demodulation 4FSK demodulates Unlike most programs envelope detector,. The baseband signal is represented with four level distinguish phase with the modulation signal.)

此程序实现了AWGN信道下的模拟调制解调，用的是matlab平台(This program implements the analog modulation and demodulation under the AWGN channel, using the MATLAB platform.)
