为了使数字信号在信道中有效地传播，必须使用数字基带信号的调制与解调，以使得信号与信道的特性相匹配。基于matlab实验平台实现对数字信号的2psk的调制与解调的模拟。本文详细的介绍了PSK波形的产生和仿真过程加深了我们对数字信号调制与解调的认知程度。-To make effective dissemination of the digital signals in the channel, must use the modulation and demodulation of the digit

曾峰的数字通信，主要包括波形成型，匹配滤波，AM调制解调，QPSK调制解调，FSK调制解调，最大似然检测等。-Digital communication has peaks, including waveform shaping, matched filtering, AM modulation and demodulation, QPSK modulation and demodulation, FSK modulation and demodulation, the maximum like
