Paper on hetrogenous network

说明：  说明：此为球形开关测试程序的上位机软件。 能够记录由下位机上传的每支球形开关 的通断情况，自动记录上传的时间， 并且会将历次的结果保存在PC机的硬盘 中，带有具体的日期，方便查询。(Note : This spherical switch to the testing procedures PC software. To record the next crew uploaded each spherical switch-off, automatically records upload time, and will keep all the previous results of the PC's hard disk, with the specific date, and easily accessible.)

说明：  提供了降低OFDM系统PAPR的一种经典算法，即PTS算法，有效抑制了系统的峰均比(A classical algorithm to reduce the PAPR of OFDM system, namely PTS algorithm, is provided, which can effectively suppress the peak-to-average ratio of the system)

一些关于bicm调制的代码，比较好的，希望对大家有用(bicm modulation)

说明：  对数字信号进行相位幅度调制，并在接收端成功解调(QAM of Digital Signal and Successful Demodulation at Receiver)
