用MATLAB进行ASK、FSK、PSK的编码和解码的仿真程序，并对其误码率进行分析-Using MATLAB for ASK, FSK, PSK encoding and decoding of the simulation program, and analyze its BER

it is a comparison between psk , ask and fsk modulation techniques about thier ber

Ask、fsk、psk各做一个调制与解调的实验仿真 再做一个三个的结果（误码率）比较，通过图像对输出结果进行对比， 每个仿真的输出结果可随输入数据的改变而相应改变 课程设计需要运用MATLAB编程实现ASK,FSK,PSK，调制解调过程，并且输出其调制后的波形，画出频谱、功率谱密度图，并比较各种调制的误码率情况，讨论其调制效果 -Ask, FSK, PSK each simulation a modulation and demodulation 再做一个三个的结果（误

MATLAB仿真ASK,BPSK,QPSK调制方式的误码率，与理论值比较(The BER of ASK, BPSK and QPSK modulation is simulated by MATLAB and compared with the theoretical value.)
