代码说明:

  数字基带传输基带信号,指未经调制的信号。这些信号的特征是其频谱从零频或很低频率开始,占据较宽的频带。 基带信号在传输前,必须经过一些处理或者某些变换(如码型变换、波形和频谱变换)才能送入信道中传输。处理或变换的目的是使信号的特性与信道的传输特性相匹配。 数字基带信号是消息代码的波形表示。表示形式有多种,有单极性、双极性波形,归零和非归零波形,差分波形、多电平波形之分,各自有不同的特点。 研究数字基带信号通过加性高斯白噪声信道的传输,并且假设信道除了叠加高斯噪声外,不会对信号产生其他失真。(matlabSimulation(pulse amplitude modulation) modulation signal in AWGN (additive white Gaussian noise AWGN (Additive White Gaussian Noise)) under the channel bit error rate and bit error rate performance, and compared with the theoretical value.)

    离散小波变换是指在特定子集上采取缩放和平移的小波变换,是一种兼具时域和频域多分辨率能力的信号分析工具。此变换运用可以缩放平移的小波代替固定的窗进行计算分析,主要应用于信号编码和数据压缩。(Discrete wavelet transform refers to the specific subset take scaling and translation on the wavelet transform, is a kind of multi-resolution ability both time domain and frequency domain signal analysis tool. This transformation can use zoom translational wavelet calculation and analysis instead of the fixed window, mainly used in signal coding and data compression. )

    说明:  Curvelet变换是由一种特殊的滤波过程和多尺度脊波变换组合而成:本程序对彩色图像进行了curvelet变换从而实现图像去噪的效果。首先对图像进行子带分解;然后对不同尺度的子带图像采用不同大小的分块;最后对每个分块进行Ridgelet分析。(Curvelet transform is a combination of a special filtering process and multi-scale ridgelet transform. In this program, curvelet transform is applied to color image to achieve the effect of image denoising. First, the image is decomposed into sub-band; then the sub-band images of different scales are divided into different sizes; finally, each sub-band image is analyzed by ridgelet.)
