Program for Space-Time-Block-Code BPSK modulation performance as a function of SNR and BER. (MATLAB)

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

自己毕设的一部分，vblast2x1、2x2和 alamouti 2x1 2x2的误码率作图比较。(vblast2x1, 2x2 and alamouti 2x1 2x2 BER plotted comparison.)

基于人群搜索算法SOA的PID参数整定，包括参数的编码，适应度函数的选取，搜索步长的确定，搜索方向的确定，个体位置的更新(Update search algorithm based on PID parameter crowd SOA tuning, including selecting encoding parameters, fitness function, the search step to determine to determine the direction of the search, the individual positions)

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)

说明：  光伏发电模型,能实现光伏最大功率点跟踪,可以跑出仿真(Photovoltaic power generation model can realize maximum power point tracking of photovoltaic)
