说明：  对片内RAM进行读写操作，通过数据的写入和读出，对RAM的操作进行熟悉。(Read and write ram on chip, and get familiar with RAM operation through data writing and reading.)

一个MIMO系统，发射方采用空时网格码编码，信道为锐利衰落，接收端已知信道情况。程序很详细，对做毕设的很有帮助。(A MIMO system, the launch party use of space-time trellis coding, channel for the sharp decline of the receiving end of known channel case. Procedures in great detail, the complete set of very useful to do.)

MFC写的2个程序，通过socket通信，上下位机的。上位机发送一个名字给下位机，下位机通过查询数据库取得电话号码传回上位机,带详细文档。(MFC write two procedures, through the socket communication, next-bit machine. PC to send a name to the next crew, the next crew by querying the database to obtain the phone numbers return PC)

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.)

实现时域与频域均衡MMSE方法的比较 采用64QAM调制(Comparison of the time domain and frequency domain equalization MMSE method)

iEEE 207 标准 信道编码相关 卫星通信(iEEE 207 standard channel coding satellite communications)

Windows系统下Modbus RTU协议从站，VB.net开发，可以直接支持研华系列采集模块的源代码(Windows systems, the Modbus RTU protocol slave, VB.net developers can directly support the of Advantech series acquisition module source code)

说明：  仿真Alamouti 的 BER 性能曲线（QPSK 调制）(Simulation BER of QPSK Alamouti STBC with two transmit and receive antenna)

直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)
