  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,而各種音頻據又日益增多的局面,本文研究小波分析在信處理方面的學依據和在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晶元等硬體設備支持下,可以有應用於實際復雜多變信源編碼。
  2. Frequency response, quantization noise, reconstruction error and its sensitivity to mismatch among adcs are studied at length in prqmf banks adc system, and the theoretic results include : ( 1 ) the distortion / aliasing functions of hybrid filter banks adc system is similar with that of switch capacitor filter banks adc system ; ( 2 ) for wide or narrow band input signal, the effective resolution of the two adc systems is 0. 51og2m bits higher than their adc ; ( 3 ) reconstruction error ' s sensitivity to mismatch among adcs of the two adc systems is reduced effectively than time interleaved adc system

    2對prqmf濾波器組adc系統的頻響、量化噪聲特性、重建誤差特性以及重建誤差對adc間的失配敏感性進行了理論分析研究,所得到的理論結果為: ( 1 )混合濾波器組adc系統與開關電容濾波器組adc系統的失真/混迭一致; ( 2 )論輸入寬帶還是窄帶信,這兩種adc系統的有解析度均比其adc提高了0 . 5log _ 2m比特; ( 3 )這兩種adc系統的重建誤差對其adc間的失配敏感性均明顯低於時間交織adc系統。
  3. The algorithm have the good one - way property, high sensitivity to initial values and good security due to the intrinsic characteristic of chaotic system and rijndael algorithm. the simulation experiment demonstrates the convenience and good hash performance ; 3 ) a new scheme of digital voice secure communication was proposed based on chaotic modulation without additional synchronization. the modulation sequence generated by chaotic logical mapping was used to encrypt the digital voice signal

    混沌系統和rijndael演算法的固有特點使該演算法具有較好的安全性、對初值有高度的敏感性以及較好的單向性能,並且易於實現,是一種有的單向hash; 3 )研究了一種需同步的基於混沌調制的字語音保密通信系統的方案,利用邏輯映射產生混沌調制序列,以該序列作為密碼對字語音進行加密處理,為了更好的隱匿信特徵,混沌調制在小波分解的基礎上,對不同的通道使用不同的參進行,並借鑒混沌掩蓋對信息信進行了限幅處理,使密文完全隨機化。
  4. The simulation results indicate that the parallel robot control can achieve much better effect than the traditional method by means of fuzzy control only if the abundant control experience and correct inference rules are available. as the simulation result showing, the anfis achieves the same satisfying effect with successful fuzzy control without requiring any control experience. the anfis can adjust the parameters of fuzzy inference system automatically and eliminate the influence of interfere signal on the base of adequate training samples
