Title
Interference-aware Co-channel Transmission over DTV Bands via Partial Frequency and Time Overlaps
Abstract
This paper studies transmission performance in a coexistence scenario when a secondary communication network is deployed in co-channel mode within TV broadcast bands. Keeping in view the differences in timing and spectral characteristics between the primary and secondary transmissions, subcarrier-level interference at the primary is computed in presence of time-and-frequency overlapped secondary transmission. This estimation is validated experimentally as well as via simulations. Specifically, the possibility of coexistent secondary transmission near the primary broadcast receivers is experimentally evaluated in an emulated DVB-T2 transmission environment. The analytical and experimental studies demonstrate that the effects of interference at the primary receiver are within tolerable range even when the secondary transmitter transmits at high power with appropriately chosen time-frequency occupancy overlaps. The benefits are further enhanced when the agility of frequency and temporal overlaps are combined with power control in the secondary network.
