Jingbo Xia · Radio Engineering of China · 2008
With the rapid development of mobile communications,the data transmission based on wideband CDMA was used widely.In order to know data transfer technology of CDMA thoroughly,this paper introduces the ensemble structure and composition of wideband CDMA.It analyzes in detail the operation principles,operation procedures and technical characteristics of such three transmission modes as circuit data transmissions,short message transmission and package data transmissions,of which advantages and shortcomings were elaborated by comparison.Finally,the actual applications of these three were investigated.The paper is to offer the theoretic basis and technical reference for the different fields using wideband CDMA net.
