ABSTRACT

This report presents the preliminary results from a feasibility study regarding the operation of secondary spectrum users within unused television spectrum. It has been hypothesized that television spectrum is underutilized, making it a candidate for dynamic spectrum access. The feasibility of using this spectrum for enabling secondary transmissions is assessed in this work, with a focus on the possibility of unlicensed devices interfering with digital TV reception. Specifically, we investigate the critical operating parameters for developing the technical rules for device operation in bands adjacent to a digital television transmission.
