用蒙特卡罗仿真研究一个通信系统的误比特率BER。假设通信系统满足条件：信源输出的数据符号是相互独立和等概的；在发射机中没有进行脉冲形成；信道是AWGN信道-Using Monte Carlo simulation of a communication system bit error rate BER. Suppose communications systems to meet the conditions: the data source output symbols are independent, and so almost the　no pulse in the transmitter in the form　channel is AWGN channel
