System scheme of speech coding plus spread spectrum communication was presented based on a full analysis of noise characteristic, attenuation characteristic and impedance characteristic of low - voltage power line. spread spectrum carrier ( abbreviated as ssc ) technology is adopted to overcome problems existing in signal transmission over power line. high quality, low rate mbe compression algorithm was used to complete speech encoding and decoding
在對低壓電力線路的噪聲特性、衰減特性和阻抗特性三個方面充分分析的基礎上,本文提出一種語音編碼+擴頻傳輸的系統總體方案,採用擴頻載波( spreadspectrumcarrier ,縮寫為ssc )技術克服電力線傳輸信號存在的問題,採用語音合成質量高並具有較低碼率的mbe壓縮演算法完成語音信號的編解碼。
