代码说明:

  Image water marking using Stationary Wavelet Transform with 3-level decomposition. The problem with DWT is lack of shift-invarience and poor spatial resolution of the resultant image. These were reduced with SWT, at the cost of memory requirements

  • MPSKTransmissonwithGausNoise
    本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分:phase.m对基带码元序列进行脉冲成型,可选矩形脉冲,升余弦脉冲和平方根升余弦脉冲; model.m 为主程序,完成各种信号的基带星座图映射、脉冲成型和调制; command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)

    HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)
