小波变换是在傅立叶变换的基础上发展起来的,它优于傅立叶分析的地方是它在空域和时域都是局部化的,其局部化格式随频率自动变换,在高频处取窄的时(空)间窗,在低频处取宽的时(空)窗,适合处理非平稳信号,在图像处理、模式识别、机器人视觉、量子力学等领域得到广泛应用。-Wavelet transform is a Fourier transform developed on the basis, it is better than Fourier analysis of the place is that

本文利用小波以及小波包在数字信号处理中表现出来的优势,将其应用到变换域通信(TDCS)中。针对基于傅里叶变换估计方法无法对非平干扰进行有效估计的缺点,于是小波技术被应用于谱估计中。作为TDCS通信前端的频谱感知阶段所应用的数学工具,进行频谱感知,小波变换可以确定干扰所在频段以及创建小波基函数,用于数据传输。并且将其与其他变换方式的应用场合以及性能进行对比。并且针第二代小波良好的数据压缩性能,拟将其应用于TDCS中,对干扰频谱进行进一步压缩-The article utilized the adv

对于非平稳信号的分析不能依靠傅里叶变换,但可以采用时频分析的方法,其中加窗傅里叶变换是最简单的一种。但是,它有很大的局限性:当基本窗函数一旦取定,窗口的时窗宽度和频窗宽度就固定了,不会随时域和频域的位移而变化。-For non-stationary signal analysis can not rely on Fourier transform, but you can use time-frequency analysis method, in which the windowed Four
