2 . reseach different methods and steps carried out including discrete cosine translation , run - length enconding and haffman encoding about signals coding and decoding . the signal - coding structure diagrams and programmable flow charts are not only established but also the applide program about signal coding and decoding is complied on vc developable flat
研究了信源編解碼的各種方法(包括dct 、游程編碼和哈夫曼編碼等)以及實現(xiàn)的步驟，建立了信源編碼實現(xiàn)的結(jié)構(gòu)圖和程序流程圖，并在vc的開發(fā)平臺下，編制了信源編解碼實現(xiàn)過程的應(yīng)用程序。
Secondly , we apply tk operator to the cross - correlation of received signal code and pn code to separate the multi - paths . it comes to a conclusion that tk operator can separate the multi - paths within less than the chip period accurately of spread - spectrum system with space - modulation by simulation . at last , we apply this algorithm to the practical signal collected by gps tap , and from the result we can drop a conclusion the tk algorithm is practical
本文首先闡述了時空調(diào)制擴頻信號原理以及在多徑干擾下時空調(diào)制接收機的性能和teager - kaiser接收機的原理;接著對時空調(diào)制擴頻系統(tǒng)的解調(diào)信號與偽碼的互相關(guān)函數(shù)采用tk接收機進行多徑分離,仿真結(jié)果表明, tk接收機對時延在一個碼片內(nèi)的時空調(diào)制擴頻通信多徑信號有很好的分離效果;最后用數(shù)據(jù)采集器對一個gps信號進行接收和多徑的估計,驗證了該算法在實際的運用中對多徑的擴頻信號有很好的分離效果。
When the speech signal coding is at 8kb / s and 9 . 6kb / s , its understanding and definition are quite satisfaction . completely achieve the common telephone effect . only in the shade of naturalness . when the speech signal coding is at 4kb / s and 4 . 8kb / s the voice transmission result is as good as that of the ordinary telephones
本文所設(shè)計的q4401應(yīng)用電路，在語音壓縮速率為8kb s和9 . 6kb s時，其語音質(zhì)量在可懂度和清晰度方面均十分滿意，完全達到了普通電話的通話效果，僅在自然度方面略顯遜色。
