Subcarrier Allocation for Multiuser Two-Way OFDMA Relay Networks with Fairness Constraints
Hanmok Shin, Jae Hong Lee · 2010
In this paper, we propose a new adaptive subcarrier allocation for a multiuser two-way OFDMA relay network. In the proposed algorithm, subcarriers are allocated to the user-pairs and relays to maximize the achievable sum-rate over all user-pairs while satisfying the minimum rate requirement for each user-pair. Simulation results show that the proposed algorithm improves spectral efficiency and fairness.
