Nested Codes in Opportunistic Scheduling Model
HU Liuju · ZTE Technology Journal · 2015
This paper introduces the concept of opportunistic scheduling in a nested coding system. In this scheme, adaptive rate nested codes are used according to channel conditions in order to increase the transmission load of the link while maintaining a good channel condition. In this way, network capacity is no longer constrained by the worst link, and the overall throughput of wireless networks is increased. Simulation shows that compared to traditional non-opportunistic scheduling nested coding, opportunistic scheduling nested coding increases throughput and reliability of single relay multicast relay networks.
