摘要
根据信息及其传输的实质建立信息传输的物理模型。用熵与互信息研究信息传输的有效性和可靠性,通过编码和编码定理得到一些重要的性能界限。最后建立了一个数学模型,进一步揭示信息传输原理及其核心理论。
According to the information and its process of transmission, the physical model of information transmission is established. The effectiveness and reliability are explored using and mutual information. The performance boundaries are acquired through coding and coding theorem. And finally a math model is established, which can explain the principles of information transmission and indicate its nucleus.
