Radio resource allocation algorithm based on selective subcarriers for OFDM relay channels

针对OFDM中继信道,本文提出了一种基于选择性子载波的无线资源分配算法。文中通过选择信道条件最好的部分子载波进行平均功率分配,并对中继子载波进行优化分配。仿真结果表明,该算法不仅能够提高系统可获取的传输速率,而且可以降低运算复杂度。

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.
