Lecture 16 : Shannon ’ s Noisy Coding Theorem
نویسنده
چکیده
W represents a message. We will often consider that it is the output of the compressor. The encoder receives W and encodes it to X. The encoder puts X into the channel and Y n is the output the decoder receives. Finally, the decoder tries to estimate W through Y . The decoder’s estimate is denoted by Ŵ . Our goal is to understand what kind of encodings are such that Ŵ is the same as W with high probability and n is as small as possible.

1. Noisy Channel: This channel introduces a noise in the data during transmission and hence the receiver gets a noisy version of the transmitted data. Therefore, for reliable communication, redundancy has to be added to the data generated by the source. This redundancy is then removed at the receiver’s end. This process of introducing redundancy in the data to make it more resilient to noise is...

The communication model we are using consists of a source that generates digital information. This information is sent to a destination through a channel. The communication can happen in the spatial domain (i.e., we need to send information over a physical distance on a channel) or in the time domain (i.e., we want to retrieve data that we stored at an earlier point of time). The channel can be...

متن کاملLecture Notes on Information Theory Volume I by Po
Preface The reliable transmission of information bearing signals over a noisy communication channel is at the heart of what we call communication. Information theory—founded by Claude E. Shannon in 1948—provides a mathematical framework for the theory of communication; it describes the fundamental limits to how efficiently one can encode information and still be able to recover it with negligib...

We study the statistics of optical data transmission in a noisy nonlinear fiber channel with a weak dispersion management and zero average dispersion. Applying path integral methods we have found exactly the probability density functions of channel output both for a non-linear noisy channel and for a linear channel with additive and multiplicative noise. We have obtained analytically a lower bo...
