CDMA BASE STATION EMULATION SYSTEM DESIGN AND IMPLEMENTATION
Abstract： CDMA (Code Division Multiple Access, Code Division Multiple Access) technology, is based on spread spectrum multiple access technology to connect. Multiple complete CDMA technology for mobile communication networks of modern high-capacity,high-quality,integrate-dservices,suchas soft-switching high-performance requirements of modern communications technology is an important direction of development.
Base Station System (BSS) mobile communication system is an important device that CDMA is a wireless cellular system with the most direct relationship between the basic component of it through the air interface directly with the mobile station is connected, in charge of wireless send, receive and wireless Resources Management. On the other hand, base station subsystems and network sub-system of mobile switching center (MSC) connects mobile users or mobile users and fixed network communications between users to connect, send the signal system and user information, provide users with A maintenance operation interface, so that the system is running a good means to maintain.
In this paper, the CDMA base station system design simulation programs and methods to achieve a simple, and the system of two major modules - radio frequency modules, baseband module to do to achieve concrete was discussed. MATLAB design of the use of powerful simulation function of the respective CDMA base station system baseband modules, radio frequency modules for simulation, the design of the concrete base of the system model. In the model of the design process, the model for the design of the purpose of the specific structure of the composition are given specific detailed description and analysis.
