SNR_MSE_analysis
小波变换(wavelet transform,WT)是一种新的变换分析方法,它继承和发展了短时傅立叶变换局部化的思想,同时又克服了窗口大小不随频率变化等缺点,能够提供一个随频率改变的“时间-频率”窗口,是进行信号时频分析和处理的理想工具。它的主要特点是通过变换能够充分突出问题某些方面的特征,能对时间(空间)频率的局部化分析,通过伸缩平移运算对信号(函数)逐步进行多尺度细化,最终达到高频处时间细分,低频处频率细分,能自动适应时频信号分析的要求,从而可聚焦到信号的任意细节,解决了Fourier变换的困难问题,成为继Fourier变换以来在科学方法上的重大突破。(wavelet transform)

(1) 数据源:随机产生752*8bit作为数据源
(2) 按照DTMB的能量扩散初始相位和生成多项式来产生伪随机数据并对原始数据源进行加扰
(3) 加扰后的数据直接进行解扰,观察误码率的值,验证加扰算法
(4) 按照DTMB标准构造BCH(1023,1013)来实现BCH(762,752)信道编码器和解码器,并观察其误码率是否为0来验证其正确性。
(5) 最后把能量扩散和BCH编码级联,接收端把BCH解码和解扰级联,观察其误码率,验证正确性。
((1) Source: randomly generated 752* 8bit as data source
(2) in accordance with the energy of the initial phase and the diffusion DTMB generator polynomial to generate a pseudo-random data and the original data source scramble
(3) the scrambled data is directly descramble, the bit error rate of the observed values, verification scrambling algorithm
(4) In accordance with DTMB standard configuration BCH (1023,1013) to achieve the BCH (762,752) channel encoder and decoder and observe its error rate is 0 to verify its correctness.
(5) Finally, the energy dispersal and BCH coding cascade, the receiving end of the BCH decoding and descrambling cascade observed error rate, to verify the correctness.)
