principles and practice of information theory
Principles and Practice of Information Theory is a field of study that deals with the quantification, storage, and communication of information. It is a mathematical framework that aims to understand the fundamental limits of communication and compression of information. The theory has its roots in the work of Claude Shannon, who developed the concept of entropy, which measures the degree of randomness or uncertainty of a signal.怎么办物流公司

The principles of information theory are bad on a few fundamental concepts such as channels, source coding, and channel coding. A channel is a medium through which information is transmitted, such as a wire, fiber-optic cable, or radio waves. Source coding is the process of compressing information so that it can be transmitted efficiently, while channel coding is the process of adding redundancy to the transmitted signal to ensure that it can be recovered at the receiver in the prence of noi and other disturbances.
