代码说明:

说明:  Welch法功率谱密度 Psd自功率谱 是用改进的平均周期图法来求随机信号的自功率谱估计 采用信号重叠分段,加窗函数和fft算法等计算一个信号的自功率谱估计(PSD)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    在背景为纯色的情况下,能够用色调来代替Alpha,而色调虽然是特效,但是他实际上只是颜色的复合,结果让文本显示单一颜色,调用(In the background for the pure color, can coloring attune instead of Alpha, and tonal though is the special effects, but he is actually the color composite, the result let text display a single color, calls)

  • FinalDSIPAPROrdinary
    The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.
