代码说明:

电脑端使用串口调试助手,选择电脑与STM32相连的COM口,设置为115200-N-8-1, 复位开发板,即可接收STM32串口发送给电脑的调试信息。 /*********************************************************************************************/ 【*】 引脚分配 EEPROM(AT24C02): EEPROM芯片的I2C接口与STM32的I2C1相连,且已接上拉电阻。 SCL PB8 SDA PB9 串口(TTL-USB TO UART): CH340的收发引脚与STM32的发收引脚相连。 RXPA9 TXPA10

    仿真程序:首先需要用一个随机发生器产生(0.1)内的均匀随机数,然后再将该序列映射到对应的幅度电平{Am}。然后将这个范围再分成4个相等的区间,这些子区间分别对应于4个信号比特的符号00,01,10,11。检测器观察到r=Am+n,并且计算r和4种可能传输的信号幅度之间的距离,它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较,差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)
