The realization of digital trunking system based on CDMA

摘要

This paper describes the differences between the digital trunking system and the cellular system and analyzes the probability realizing the function of the digital trunking system by the way of CDMA. Firstly, this paper discusses the scheme of the realization, and analyzes the remaining of the system which adopts the typical parameters of WCDMA, then estimate the parameters with the two transmission models--Okumura and Egli, and the graph of the remaining in the systems is given.
