16QAM

mimo_ofdm快速时变的一种低复杂度的检测算法在PDF通道，他涉及MIMO-OFDM的基本知识及应用。(Mimo_ofdm fast time-varying a low complexity detection algorithm in PDF channel, basic knowledge and application he relates to MIMO-OFDM.)

说明：  8. 单径瑞利信道中的四发四收V-BLAST： (1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量16QAM调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。 (2) 计算所设计方案的频谱效率是多少，单位为bit/Hz/s。(8. Four transmit four receive v-blast in single-path Rayleigh channel: (1) please design a specific navigation-assisted channel estimation method and conduct simulation with Simulink to measure the bit error rate performance of 16QAM modulation.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn. (2) calculate the spectral efficiency of the designed scheme in bit/Hz/s.)

OFDM通信系统抗多径衰落干扰研究,顺便求OFDM系统中关于频谱偏移的估计与补偿的，(OFDM communication system of anti-multipath fading interference studies, the way for OFDM systems on the spectrum offset estimation and compensation,)

对无线通信环境下的多径衰落和阴影衰落进行的建模。给出了一些仿真的建议(Modeling on multi-path effect and shadowing under wireless communication system. And this code gives some advice on simulation of these situation.)

说明：  To completely remove inter-cell interference, SIC is applied by the receivers at the user side. The technology can separate these data streams for corresponding users The interference cancellation technology is of importance for hybrid unicast/multicast service system performance

关于阵列信号处理窄带DOA估计的MATLAB仿真程序，用于学习比较（Capon,convention,MUSIC,DML）(Narrowband array signal processing for DOA estimation of the MATLAB simulation program for learning more (Capon, convention, MUSIC, DML))

modbus 详细解说，协议文档。。。,包括了function。。。(modbus detailed explanation of the protocol documentation. . .)

用visaul basic 编写的,连接Wsdl服务的例子(Written visaul basic example connect Wsdl service)
