基于小波包分析的ATM网分层传输
ATM Network Delamination Transmission Based on Wavelet Packets Analysis
【摘要】 针对DCT固有的方块效应以及小波变换存在“高频低分辨”的缺点,该文提出基于小波包分析的ATM网分层传输,并用MATLAB工具箱实现实验。结果表明:小波包分层法适合ATM网络中多种业务传输的要求。
【Abstract】 Aimed at intrinsic square blocks of DCT and the defect of″high frequency but low differentiation-rate″exist-ed in wavelet transformation,the paper presents the ATM network delamination transmission based on wavelet packets analysis.MATLAB toolbox can realize the experiment.The result shows that wavelet packets delamination method adapts to the need of comprehensive transmission in the ATM network.
