PC机与智能仪器串口通信,通过串口对温度值进行采样，计算最小值，最大值，平均值,PC machines and intelligent serial communication apparatus through the serial port on the sample temperature to calculate the minimum, maximum, average

由信道信号的复数值找出对应的二进制序列。方法如下：由信道值，求出该值与星座图中所有点的距离，找出距离最小的点，该点对应的二进制序列及为该信道对应的解调结果。-this program is used for BPSK,QPSK,16QAM and 64QAM demodulation.

分别编写求两个数值（可以是浮点数，整数或字符）最大值，最小值和平均值的函数maximum, minimum, meanValue。另外，编写一个函数gcd求两个整数的最大公约数。-Respectively write to demand the two values ​ ​ (which can be floating-point, integer or character) maximum, minimum and average function of the maxim
