In this paper, the problem of feedback and active user selection in MISO wireless systems such that the system's stability region is as big as possible is examined. The focus is on a system in a Rayleigh fading environment where Zero Forcing precoding is used to serve all active users in every slot. Acquisition of the channel states is done via uplink(More)
In broadcast and multicast systems, Video programs are transmitted over a constant bit rate channel. Apart from bandwidth constraints, the control of each encoder involved in the statistical multiplexing has to satisfy several other constraints: minimum quality, fairness, and smoothness constraints. This paper proposes an improved control scheme for(More)
—Video streaming is considered one of the most important and challenging application for next generation cellular networks. Current infrastructures are not prepared to deal with the increasing amount of video traffic. The current Internet, and in particular the mobile Internet, was not designed with video requirements in mind and, as a consequence, its(More)
—This paper proposes a control scheme for the quality-fair delivery of several encoded video streams to mobile users sharing a common wireless resource. Video quality fairness, as well as similar delivery delays are targeted among streams. The proposed controller is implemented within some aggregator located near the bottleneck of the network.
