the codes which i sent contains matlab code for encryption using 4 out of 8 code,binary to decimal conversion,decimal to binary conversion,subband coding,upsampling.

使用电压矢量控制策略，可以并网运行。调节电网电压，跟踪性能好，是MATLAB 2010的版本，大家可以参考(The use of voltage vector control strategy of grid connected operation, can. Grid voltage regulation, good tracking performance, is the 2010 versions of MATLAB, you can refer to)

预失真补偿后的图形,采用快速傅里叶变换（Fast Fourier Transform, FFT） 计算得信号的频率数据，再利用得到的频率数据计算功放预失真补偿前后功率谱密度 样值(Predistortion compensation of graphics, using the Fast Fourier Transform, Fast Fourier Transform and FFT) Calculate signal frequency data, then get the frequency of the power spectral density before and after data computing power amplifier predistortion compensation Sample values)
