Abstract

Software Radio is seen as one of the key facilitators of third generation mobile telecommunication systems. Ultimately it can be perceived as an evolution and convergence of existing digital radio and software technologies, and not as a completely new technology. The objective of this paper is to characterize the various implementation considerations with regard to software radio, including a brief R&D perspective. It focuses mainly on the issues surrounding software radio implementation - What drives it? What holds it back? The different implementation aspects include those on a system level such as network capabilities, handset/base station issues and power control, and critical component technologies like ADC, DSP and RF functionality. Finally, an assessment of the current developments is presented, resulting in a number of conclusions on whether software radio is “to be or not to be?”.
