纠错码在数字通信中的应用

Applications of error--correcting codes in digital communication

随着通信系统数字化和VLSI技术的进展,纠错码得到了日益广泛的重视和应用,成为数字通信系统设计中的一项重要技术。文中介绍纠错码性能的理论限在各种数字通信中的具体应用,以及用VLSI芯片实现编译码器的发展近况。

With the digitalization of communication systems and the development of VLSI tech- niques, error--correcting codes are being widely used and become a very important technique in the design of digital communication systems. In this paper, we shall introduce the theoreti- cal performance bounds of error--correcting codes, their applications in various digital commu- nication systems and the recent progress of the implementation of encoder/decoders with VLSI chips.
