Sinusoidal-Signal-Generation

这是基于小波变换的数字水印代码，在嵌入的水印加上一个pn尾随机序列(This is based on the wavelet transform digital watermark code, the embedded watermark with a random sequence late pn)

运用matlab实现数字滤波器，主要是采用的频率采样法(Realize the use of matlab digital filter is mainly used in the frequency sampling method)

在认知无线电中，频谱感知频谱分配是两个主要问题，而动态频谱接入是理解频谱感知的关键。(In CR, spectrum sensing and spectrum allocation is the major problem, but the dynamic spectrum access is the key to understand spectrum sensing.)

Matlab7基础与提高下载资料,很详细，书中的例程都包括在内了(Matlab7 base and improve the download information, very detailed, the book' s routines are included in)

为了研究系统在受到外界干扰情况下的性能，特别从输入端加入了噪声干扰，仿真效果明显。(this progrmme is set to test the system performance .)

说明：  Ux profile in boundary layer

matlab实现的fft算法，可以与自带的代码比较，功能基本一样。(err)
