“…In our work, we focus on the SDR technology and applied this approach as the mechanism for seamless switching between different standards: UMTS and WiMAX [15]. We believe that SDR technique allows to reprogram and reconfigure our system by using a software function, which should be written in a special library.…”

In this work, we are proposing a novel approach targeted to handling signal processing and data transmission tasks related to a multi-standard terminal encompassing WiMAX and UMTS standards. We shall present an innovative Software-Defined-Radio (SDR)-based framework which will be able to arrange the digital processing tasks concerning the baseband level of the multistandard transceiver architecture. In particular, an objectoriented model will be proposed for the baseband level implementation. The general structure consists of a number of modules for each specific and/or common component of UMTS and WiMAX signal processing chain. We start to design the SDR architecture model as a software prototype. The framework model was built as C++ class library in order to evaluate how SDR-based implementation works and to assess its quantitative performances. This model allows to consider the process of the packet interaction between transmitter and receiver and, moreover, the interpacket interaction inside each module of the terminal. After all, the proposed software model will be integrated into the hardware platform and the final tests will be performed.12
