Matlab高斯信道条件下采用QPSK和8PSK时点到点通信系统的理论和统计所得的误码率和误比特率曲线。 删余卷积码的Pb性能仿真 加入信道编码模块，绘制误比特率曲线,其中信道为加性高斯白噪声，调试为QPSK； 进行软判决和应判决，和用3/4、7/8删余码进行编码等。(Matlab gaussian channel conditions using QPSK and eight PSK point to point communication system theory and statistical the error rate and bit error rate curve. Delete the convolution code more than Pb performance simulation Join channel coding module, draw bit error rate curve, which channel to additive gaussian white noise, commissioning for QPSK In the soft decision and judgment should be, and with more than 3/4, 7/8 delete code for coding, etc. )
