音頻定位技術作為一門新興的邊緣交叉學科，涉及聽覺心理學、聽覺生理學、人工智慧和高性能計算機系統等多個研究領域，且具有廣泛的應用前景，它可以幫助傳遞和識別可視信息，增強三維模擬環境的逼真度、想像力和沉浸感，在軍事和民用方面有廣泛的應用。Our object is an intermediate frequency modem of a software defined radio transmitter - receiver of multi - service, multi - modulationmode and multi - processdatarate. first, related software defined radio theory is introduced ; later, channels of transmitter - receiver are designed with consideration of data format, modulation, fec, interwaving. and scrambling ; emphasis is placed on theory and implementation of an audio compression algorithm cvsd ( continuous variable slope delta modulation ) and a fec technique convolutional coding - decoding
本文首先介紹了相關的軟體無線電理論；然後完成了包括數據格式，調制方式，糾錯碼方式，交織器和擾碼器等部分的中頻數據機通道設計；接著著重介紹了系統中使用的音頻壓縮演算法cvsd （連續可變斜率增量調制）的原理和實現，以及作為前向糾錯碼的卷積碼編碼理論和編解碼的高效實現。The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way. using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range. lt is not only improved testing precision and develop the system expediently, but also reduced the area of the circuit boardwith the new way. in order to make the electric implement safety testing system have upstanding expansibility, the software and hardware of the system adopted the modularization design. adopted mcu atmegal28 as a master mcu which control mmi, realtime clock and communication with slaver mcu. atemga8 as the slaver mcu to realize testing function. so it is easy to add or reduce the testing project. the testing implement system has been developed successfully, and the comments for the system is that it has high precision, high expansibility and easy maintain. but considering the electric implement system should have intelligence and humanity abi lity. so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control. after introduce the basic theory of speech recognition, the paper expatiate the characters of this system. the system is a noise conditon, not special people, small glossary, insulation word system. with these characters design the speech recognition as fellow. utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw. in order to ensure the credibility of this project, first realized by matlab in computer
在介紹了語音識別的基本原理后，闡述了本系統的特點：本系統是一個噪聲環境下非特定人、小詞匯量、孤立詞的語音識別系統。根據本系統的這些特點設計了如下語音識別方案：利用過零率和短時能量相結合的方式確定語音端點；採用mel頻率倒譜系數（ mfcc ）作為語音識別的特徵參數；得到的特徵參數最後通過動態時間規整（ dtw ）的模式識別方法進行識別。為了確保本系統實現方案的可靠性，首先通過計算機利用matlab軟體來模擬，在演算法模擬實現后又進一步增加環境的復雜性：加上較大的環境噪聲、突發性的噪聲等，再通過修改參數、修改參考模板、兩級識別等各種提高語音識別精度的方法來提廣東工業大學工學碩士學位論文高識別率。In connection with the problems existing in the diversified economy of electricity industry and the triple - netwoerk developing trend of communication technology and the regional superiority of electric power communication network, it was recommended that electricity industry take the golden opportunity of urban and rural network modification to build a integrated network with which the voice, data and video information can be transmitted simultaneously. a new economic growing point can be formed by entering the telecommunication market
針對電力系統多經產業存在的問題，結合信息技術「三網合一」的發展趨勢和電力通信網路的區域化佔有優勢，提出了電力企業應抓住兩網改造的機遇，建立語音、數據、視頻信息一體化傳輸的綜合信息網路，進入電信和數據業務市場，實現新的經濟增長點。Same frequency repeater
