Abstract
In this thesis, we explore the potential advantages of collecting more received signal power through the use of multiple radios. A software radio is designed along with algorithms to combine the signals from multiple radios to allow reception of a signal in situations where it would be impossible with a single radio due to insufficient received power. Three techniques are explored to combine signals at different stages of decision-making. The first technique involves combining signals before calculating a single decision statistic. The second technique focuses on combining signals after calculating multiple branch statistics, leading to a composite symbol decision. Lastly, the third technique examines combining signals after multiple branch symbol decisions have been made. This may be of benefit in situations where increased range, covertness, or many small antennas are preferred to a single large antenna.
