  • Abstract
    This letter considers applying superposition coding (SC) in collaborative primary-secondary spectrum sharing environments where the secondary transmitter acts as a relay of the primary signal and is allowed to transmit its own signal only if it is not harmful to the primary transmission. Time and power allocation is optimized and numerical comparison shows that the proposed approach makes significant improvement in the achievable secondary rate.
