SDR application for implementing an integrated UMTS/WiMAX PHY-layer architecture

Abstract

Emerging standards in the area of mobile services, such as Worldwide Interoperability for Microwave Access (WiMAX) and Universal Mobile Telecommunication System (UMTS), require new capabilities from mobile devices. As a result, these devices should know how to download and correctly install reconfigurable modules. For this purpose, the Software Defined Radio (SDR) technology is used at present. SDR allows co-existence of different independent standards, protocols, and services. This signal processing approach is widespread due to the great importance of reprogramming and reconfiguring of mobile devices. Because of the availability of SDR technique in device architecture, a user can update and replace necessary services without changing hardware. In this paper, we present a new solution of SDR implementation for UMTS/WiMAX system. Furthermore, we consider common blocks in our system in detail and demonstrate the implementation of the framework model in object-oriented style using SystemC.
