| 摘 要： | 在深入分析了仿真结果后,本文发现引入应用层Raptor FEC技术,将在无线传输方面(物理层)带来了最优操作点,在最优操作点及其附近,无线资源的利用率得到进一步的提高,且无需增加发射功率以降低BLER目标值.也就是说,采用同样的发射功率,在应用层使用了Raptor FEC编码技术之后,MBMS业务的覆盖面积可进行较大幅...

| Abstract: | This paper focus on application layer cross-layer optimization for wireless video service.Having analyzed related simulation results and corresponding numerical results,we find that application layer Raptor FEC brings optimal BLER operation points for MBMS service.It means that some small FEC overhead will improve spectrum efficiency obviously and introducemoreradio resource savings,which isthe bottleneck ofthe radio network.Thisisveryhelpful for operator to expand the coverage of video service area.Moreove... |
