摘要
近年来随着通信领域的飞速发展,香农理论在编码器的设计中越来越重要,本文基于香农映射理论的思想,利用香农映射曲线,设计了一种用于语音信号的信源信道联合编码器.该编码器结构简单,易于实现,并且能够有效地利用带宽.
As the dramatic development of the the communication industry in these decades, the Shannon＇s mapping theory is more and more important in coder designing. Based on Shannon＇s mapping theory, a joint source channel coding for speech signal is designed by using the Shannon mapping curve in this paper. The structure of this joint source channel coder is simple, and the coder is easy to implement. Besides, it is an effective method to improve the bandwidth utilization.
