Abstract [en]

The work presented in this report treats the concept of software radio receivers, concentrating on a Direct-Sequence Spread-Spectrum (DSSS) application. The software radio technology is a realistic approach to fulfil the third-generation wireless communication concept of global standardization, due to the possibility of software reconfiguration. The work conducted is a preliminary study into a reconfigurable software radio receiver, which could be a useful tool when studying the application of adaptive antennas to Generation 3 mobile radio systems at the Centre of Telecommunications and Information Engineering (CTIE) at Monash University. With focus on a base station, the work has been aimed towards the reverse link in the European Telecommunications Standards Institute-WCDMA (ETSI-WCDMA) standard. The study shows that the possibility to implement an ideal (ultimate) software radio receiver is limited by the available hardware, ie the Analog-to-Digital Converter (ADC) and the Digital Signal Processing (DSP) device. It is further shown that by utilizing a conventional analog front-end and the concept of undersampling, a functional software radio receiver implementation can be achieved. To point out the possibility of software reconfiguration, three different receiver designs were implemented and simulated in a Texas Instruments (TI) TMS320C6201 Evaluation Module (EVM) DSP, which was the available processor. To validate the functionality of each receiver, acquisition detection probability- and Bit Error Rate (BER)-simulations in an Average White Gaussian Noise (AWGN) environment were conducted.
