通信的数学理论

Shannon的通信的数学理论一文，标志了编码理论的开始，同时也证明了好码的存在。

The article " A mathematical theory of communication " by Shannon , made the beginning of coding theory , and also proved the existence of good codes .

1948年，香农[2]在他的论文通信的数学理论中，首次阐明了在有扰信道中实现可靠通信的方法，提出了著名的有扰信道编码定理，奠定了纠错码的基石。

1948 , Shannon clarified the noised channel code theory in the thesis " A Mathematical Theory of Communication " , which is the foundation of error-correcting codes .

自香农（Shannon）1948年发表了论文《通信的数学的通信理论》以来，信道编码的发展取得了很大成就。

From the thesis " the theories of mathematics in communications " announced by Shannon in 1948 , the coding in channel has obtained very great achievement .

本文介绍了扩频通信的数学模型、基本理论、系统构成，分析和给出它的关键技术及实现构想。

This paper introduces the mathematic model , basic theoretics and system structure of Spread spectrum communication , analyzes and gives its key techniques and implementation thought .
