Research And Design Of CDMA Digital Wireless Transceiver With No Central Control

As the nucleus-theory of third generation mobile communication, the code division multiple access technology is widely applied in public cellular mobile communication network. But considering another important part in the field of mobile communication, that is no center mobile communication network (such as interphone) have been developing more slowly in recently twenty years. Now, the artery no center facilities also regard frequency division multiple access as core, adopt analog modulation mode, the application of code division multiple access is not discussed at all.This subject is put forward based on above background. In this paper, the probability of combining code division multiple access and no center mobile network is researched, the design target is that constructing a universal intermediate frequency digital communication platform make code division multiple access technology well applied in no center mobile network through appropriate software.Firstly, in this paper, several kinds of familiar multiple access technologies are summarized, their advantages and disadvantages are analyzed. At the same time, the advantages of CDMA relative to other multiple access technologies are indicated.
