通信系统中的天线选择，包括信道的搭建，功率的分配。(Antenna selection in a communication system, including the allocation of the channel structures, power.)

关于视频质量评测内容，宏块级的SSIM值计算(Video quality evaluation on the contents of the macro block level SSIM value)

psk modulation for cma blinder equeliser

基于matlab2011b，接三相独立负载，给需要的朋友分享。(Based matlab2011b, connected three independent load to the need to share.)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

说明：  用matlab画电场,MATLAB与FDTD联合仿真，绘制出电场磁场电流分布图(Matlab to draw the electric field)

sinusoidal pulse width modulation technique, power systems

说明：  经典的dv-hop算法实现无线传感器网络的定位，还有节点分布图和定位误差图(Dv-hop classic algorithm wireless sensor network localization, as well as node distribution and the positioning error map )
