Design and Simulation on Channel Coding with Matlab
Abstract: With the development of computer and communication technology, the storage and exchange amount of digital data increase dramatically, which requires a higher reliability for data transmission. Nowadays, the development of VLSI, modern algebra and computer simulation technology establish the basis on which the theory of Error-Correcting Codes is improved. As a result, several practical Error-Correcting Coding technologies have been found. In the future network and information age, it can be expected that Error-Correcting Code will gain its wider application, and the research and develop work of it will have high practical value and profound meaning.
Channel coding technology, as an important method of the anti-interference technology, plays a more and more important role in the field of digital communication technology and the system of digital transmission. This article briefly describes the channel coding theorem, detailedly declares the compiled principle, realized method and the capability of error detection and error correcrtion for the group code and convolution code, and describes how to use matlab to simulate some influence of the communication system performance in different channels. 源自六-维+论\文"网*加7位QQ3249.114 www.lwfree.cn
