Design and Implementation of a Variable Message Format Coding and Decoding Module
摘要
Abstract
In order to adapt to the military requirement of modern war digitization and solve the problems of increasing amounts and types of information need to be transmitted in the battlefield environment and con-strained network bandwidth,a decoding module of variable message format( VMF) is designed as the tech-nical support of underlying message. Using dynamic link library,Java Script object notation( JSON) ,Snap-py and other technology,it can provide the service of message codec for the upper application. The design is based on the template of JSON,bit stream integrated compression algorithm and the data dictionary struc-ture JSON,and then realizes the message sent"on demand" and the combination of dynamic message con-tent according to the different delivery requirements. The experiment shows that coding and decoding only takes about 3 ms in the designed module,while the original decoding system takes over 200 ms. Obviously, it can increase the rate,and further shorten the length of the encoded data stream.关键词
