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 be aware of how to download and correctly install particular software. For this purpose, the Software Define Radio (SDR) technology is used at present. SDR allows co-existence of different independent standards, protocols, and services. This signal processing approach is broadly spreading given that reprogramming and reconfiguring of mobile devices is of great importance. Due to the availability of SDR in the device architecture, a user can update and replace necessary services without changing the hardware. This work presents a new approach to adaptation of WiMAX and UMTS to the mobile terminals on the basis of SDR. We propose the original implementation of the signal processing phase which will be able to dynamically support incoming signals of different standards.
