A Novel Spectrum Sharing Scheme Using Relay Station with Intelligent Reception
Abstract
In this paper, we propose a new spectrum sharing method using relay station with intelligent reception at the receiver. The relay station retransmits primary signal to destination which receives combined primary and secondary signals simultaneously. Then, the receiver detects the secondary signal by cancelling the primary signal out with the aid of the relayed signal. Simulation results demonstrate that the proposed method guarantees reliable communication for secondary service between some pairs of users, where there is another licensed primary service in the same frequency band.
