Abstract :
In this paper, joint time-frequency subchannel pairing is investigated for buffer-aided multirelay OFDM networks. Closed-form expressions for the outage probability and symbol error probability are obtained. Lower and upper bounds for the capacity are also given. Simulation results validate our analysis and show that joint time-frequency subchannel pairing can significantly improve the performance of the system.
