Introduction 介绍


The recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication.

最近,对于调制的多种方法的开发,例如 PCM 和 PPM,在通信的一般理论中,他们增强了对带宽将信号转到噪声比率的兴趣。

A basis for such a theory is contained in the important papers of Nyquist and Hartley on the subject.

关于这个主题的一个理论的基础包含在 奈奎斯特(Nyquist) 和 哈特利(Hartley) 重要的论文中。

In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible duo to the satistical structure of the original message and duo to the nature of the final destination of the information.

在本文中,我们将扩展这个理论,以包含一些新的因素,特别是信道中噪声的影响,和由于原始消息的结构 和 由于信息的最后目的地的性质 造成的可能剩下的信息。
