| Abstract: | For OFDM relay channels,this paper proposes a novel radio resource allocation algorithm based on selective subcarriers.In this method,parts of the subcarriers with the best channel conditions are selected and allocated with equal power,and then relay subcarriers allocation is optimized.Simulation results show that the proposed algorithm can not only improve the system achievable rate,but reduce the computational complexity. |
