Popis: The Software Defined Radio (Sdr) has always been considered as a promising solution for the future of wireless communications because of its ability to provide flexible architecture, enabling multimode and multistandard devices. On the network side, this technology seems to be achievable in a short-term visibility (we even are currently knowing the very beginnings ofSdr solutions in the field of network equipments), but applied to terminals, this technology is likely to reach later its maturity because the embedded issue is synonymous with high constrained architecture. The implementation of software radio terminals requires, for instance, the use of high calculation capability Digital Signal Processors (Dsp) or deeply integrated multiband rf transceiver, whose power consumption quality acts as a brake for the current development of such solutions. Nevertheless, the microelectronic industry will still provide more and more powerful components and, within a few years, theSdr dream will come true for terminal manufacturers. Furthermore, software radio is also a good opportunity to merge computer science and telecommunications technologies, in order to develop smart terminals, which may integrate software components like an operating system or Java virtual machine, etc. Hence, the software radio concept within mobile terminal is still an R&D issue, which requires effort combination in different fields but which also represents a great opportunity for the future of terminals.
