dc.description.abstractThe continued advancement and improvement of software-defined radio technology has been a key factor in furthering research into the implementation of most signal processing algorithms at baseband. Traditionally, these algorithms have been carried out at RF, but with the coming of SDR, there has been a need to shift the processing down to baseband frequencies which are more compatible with the fast developing software radio technology. The study looks at selected demodulation algorithms and investigates the possibility and benefits of carrying them out at QBB. The study ventures into the area of beamforming, multipath compensation, Doppler shift compensation and matched filter detection. The analysis is carried out using Matlab simulations at RF and QBB. The results obtained are compared, not only to evaluate the possibility but also the benefits in terms of the processing load. The results of the study showed that indeed, carrying out the selected demodulation algorithms at QBB was not only possible, but also resulted in an improvement in the processing speed brought about by the reduction in the processing load.en_ZA
