摘要
数据压缩技术就是将较大的数据量压缩为最少的数码,从而更加便捷地表示信号,可以用于数字通信、存储、多媒体娱乐等方面。采用数据压缩技术提升信号传输效率,现有通信干线利用该技术不仅可以并行更多多媒体业务,还可以将数据存储量紧缩,使发信机功率降低,让多媒体移动通信系统更加稳定便捷。数据压缩并不是一种新技术、新思路,该方法的种类有很多,但大部分都缺少适用性。数据压缩研究主要分为两个发展方向,一个数学家研究,以建立信源和数据压缩数学模型为主;另一个是工程技术人员研究,主要构建可以实现数据压缩功能的系统。文章主要介绍了数据压缩技术的发展,阐述了LZSSB算法在数字信号处理中的应用,希望能为数据压缩技术的推广提供参考。
Data compression technology is to compress a large amount of data into the smallest number,so as to express signals more conveniently.It can be used in digital communication,storage,multimedia entertainment,etc.The use of data compression technology can improve the efficiency of signal transmission.The existing communication trunk can not only use this technology to parallel more multimedia services,but also compress the data storage,reduce the power of the transmitter,and make the multimedia mobile communication system more stable and convenient.Data compression is not a new technology or idea.There are many kinds of methods,but most of them lack applicability.The researches on data compression are mainly divided into two development directions.One is the research of a mathematician,which focuses on establishing the mathematical model of information source and data compression.The other is the research of engineers and technicians,mainly building a system that can realize the data compression function.This paper mainly introduces the development of data compression technology,and expounds the application of LZSSB algorithm in digital signal processing,hoping to provide a reference for the promotion of data compression technology.
