基本调制识别。识别2ask，2fsk，2psk，4ask，4fsk，4psk。-The basic modulation recognition. Identification 2ask, 2fsk, 2psk, 4ask, 4fsk, 4psk.

4元FSK调制输出功率谱，基带码元传输间隔0.1s，FSK调制参数的频率间隔分别设置为5HZ和20Hz，-4 yuan FSK modulated output power spectrum, the baseband symbol transmission interval of 0.1s, the frequency interval FSK modulation parameters are set to 5HZ and 20Hz,

基于神经网络对数字调制信号2ASK、2FSK、2PSK、4ASK、4FSK、4PSK进行门限值的判定来识别这六种数字调制信号。-Based on neural network digital modulation signal 2ASK, 2FSK, 2PSK, 4ASK, 4FSK, 4PSK threshold determination performed to identify the six digital modulation signal.

产生4FSK调制信号的函数，可以设置载波频率，采样频率。(The function of generating 4FSK modulation signal can set carrier frequency and sampling frequency.)
