程序使用了自相关性和互相关性较好的gold码作为扩频序列，直扩，扩频增益设置为31，模拟用户数为4(Program uses a self-correlation and cross-correlation of the better gold code as spreading sequence, direct expansion, spreading gain is set to 31 to simulate the number of users of 4)

说明：  仿真了MIMO通信系统的两种经典检测算法，迫零和最小均方误差，计算了误码率并绘制了误码率曲线(Two classical detection algorithms, zero forcing and minimum mean square error, are simulated in MIMO communication system. The BER is calculated and the BER curve is drawn)

GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more and more prevalent due to the ease with which they can be implemented, but the dynamic IP address issues associated with GPRS networking continue to frustrate system integrators.

说明：  用于信捷PLC与Labview之间的通信，可以作为学习的初版(Used for the communication between Sinjie PLC and Labview, it can be used as the first edition of learning.)

说明：  基带信号bpsk仿真，基带传输基本方波信号、sinc信号，对过程添加高斯白噪声，接收端用匹配滤波器进行接受，计算实际信号误码率，并于理论误码率进行比较(BPSK simulation of baseband signal. Baseband transmits basic square wave signal and sinc signal. Gaussian white noise is added to the process. Matched filter is used to receive the received signal. The error rate of actual signal is calculated and compared with the theoretical error rate)
