  1. 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晶元等硬體支持下,可以有應用於實際復雜多變信源編碼。
  2. In direct torque control system, speed sensors are usually used to survey the speed of motor, but speed sensors have many disadvantages, such as inconvenient fixing and maintenance, inaccurate precision. at present it is an efficient and feasible method to estimate speed by using software instead of hardware

    以往在直接轉矩控制系統中採用速度傳感器檢測速度信,由於測速裝置具有安裝不便、維修困難、測量精度差等缺點,因而採用軟體代替硬體檢測辨識速度,即進行速度傳感器的計,不失為一種有可行的速度辨識方法。
  3. 1 ) realization of software packet embedded in m - es and md - is respectively to accomplish main function of mdlp, including assignment of tei ( temporary equipment identifier ), establishment of multiple frame operation, framing, flow control and error - free transmission of packets, is detailed. 2 ) a test model is established to evaluate the robustness and stability of mdlp and verify the validity of software packets. 3 ) according to the design of radio modem construction used in m - es, the modules of interface between data terminal equipment and radio modem are achieved to enable transmission of short message and continuous pseudo - random bit stream via rs232 uart
