| Abstract: | The performance of the Voice over Internet Protocol(VoIP) service in the third generation(3G) long-term evolution(LTE)-Advanced relaying networks is researched.Based on the Modified Largest Weighted Delay First(MLWDF) scheduling criterion,an optimized VoIP scheduling algorithm is proposed.To analyze the performance of the algorithm,a Time Division Duplexing(TDD) system simulation platform is constructed.In the simulations,different number settings of Physical Downlink Control Channel(PDCCH) and relay nodes ... |
