Designing of Software Simulation Test bed for 3G Wireless Communication System

In this paper software is developed for wireless communication test bed which simulates a 3G Wireless Communication System using Wideband Code Division Multiple Access (CDMA) link. CDMA is a popular technology in cellular systems due to its superior capacity and performance. The designer of CDMA systems has a wide array of signal processing algorithms to choose from and a variety of operating environments to deal with. The test bed is a tool to evaluate these design options and trade-offs in different scenarios. The backbone of this system is a wireless WCDMA multiuser link built using Simulink and Matlab. We investigate the bit error rate at both uplink and downlink for different channel conditions. The software test bed developed can be an invaluable tool for learners and researchers for investigating the design and implementation of 3G Wireless Communication systems.
