Abstract

We consider a relay-assisted wireless communication system where relays are given the capability of scheduling function. We evaluate and compare the performances of voice over internet protocol (VoIP) in orthogonal frequency division multiple access (OFDMA) systems where two different scheduling capabilities of relays are employed in each system. In the system with relays that have the scheduling capability, channel-resource allocation is not performed efficiently, which results in degraded performance of the system compared to the system with the relays that do not have the scheduling capability as shown in the simulation result.

基于ofdma系统中继能力的VoIP性能分析
我们考虑了一种中继辅助无线通信系统,其中中继具有调度功能。我们评估和比较了正交频分多址(OFDMA)系统中语音网络协议(VoIP)的性能,其中每个系统中使用了两种不同的中继调度能力。仿真结果表明,在具有调度能力的中继系统中,由于信道资源分配效率不高,导致系统性能比不具有调度能力的中继系统性能下降。
