In all kinds of complicated network, oriented linking and unlinking, communication frequency resource is strained, and bandwith to transmitting audio frequency signal is too restricted, complicated and fluky, while audio frequency data exponential have been increased in the last several years. under the circumstances, based on the research of predecessor, this paper studies wavelet analysis ' s maths gist and practices significance on signal process, and puts forward a optimized wavelet package condensation arithmetic to process audio frequency data, which gives attention to coding efficiency, multirate and compression delay. simulation experiment on the arithmetic has been done by matlab
針對無連接和面向連接的各種復雜網路環境下,通信頻帶資源緊張,音頻傳輸帶寬有限且復雜多變,而各種音頻數據又日益增多的局面,本文研究小波分析在信號處理方面的數學依據和在數據壓縮方面的實際意義,在前人不斷工作的基礎上,提出了一種優化小波包變換編碼方案用於音頻數據的壓縮演算法,兼考慮了編碼效率、多碼率和壓縮時延多個方面,並在matlab環境下做了模擬實驗,對各種音頻信號及多種小波函數做了模擬結果比較,實驗結果證明該演算法可以在一定計算復雜度下可以很好地改進壓縮效果,達到多碼率下實現實時編解碼的過程,在高速dsp晶元等硬體設備支持下,可以有效應用於實際復雜多變信源編碼。Based on this model, an application level layer - based congestion avoiding mechanism using by multicast is given. it takes advantage of layered video coding, sets down a set of video transfer scheme with different bandwidth
利用視頻編碼的特點,將視頻數據編碼幀按不同的壓縮比劃分為多個層次,並制定出相應的佔用不同帶寬的多層視頻編碼傳輸方案。
