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。Because the physical distance between ouns and olts in apon is different from each other, and the transmission distance will undergo dynamic changes as a result of the variation in environmental temperature and the aging of optoelectrical appliances, the differences in the uplink transmission delay will cause an overlay of the uplink time slots of onus, thus leading to the collision of different atm cell flows
由於apon中各onu與olt之間的物理距離各不相同，並且其傳輸距離也會由於環境溫度的變化和光電器件的老化等因素而發生動態的改變，引起上行傳輸時延差異造成各onu的上行時隙重疊，從而導致不同的atm信元流發生碰撞。Cell delay variation is not controlled in this service, although admitted cells are not delayed unnecessarily
在這項業務中，信元延時變化不受控制，盡管得到承認的信元並沒有不必要的延時。
