We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
The next generation wireless communication systems needs not only to provide a higher data throughput but also to support integrated applications with various quality of service (QoS) requirements. In this paper, a new cross layers design of a dynamic resource allocation control for 3GPP2 1xEV-DV systems is proposed. The dynamic resource allocation proposed is able to allocate the optimal combination...
