PAM pulse amplitude modulation , code matlab

模拟数字基带系统在matlab下的实现，包括输入输出信号的码型，功率谱密度，眼图及误码率(Analog-to-digital base-band system in the realization of matlab, including the code input and output signal type, the power spectral density, eye diagram and bit error rate)

H = CHILD returns the handle to a new CHILD or the handle to the existing singleton*. CHILD( CALLBACK ,hObject,eventData,handles,...) calls the local function named CALLBACK in CHILD.M with the given input arguments. CHILD( Property , Value ,...) creates a new CHILD or raise
