Optimal bit allocation under multiple
We present a new Lagrangian-based iterative technique for rate{distortion optimization under multiple rate constraints. We show how for sets of \lin-ear" constraints this technique can be proven to be optimal up to a convex hull approximation. As an application we consider the problem of optimal buuer-constrained bit allocation. Our technique can be used to nd an excellent approximation to the ...
متن کاملJoint Resource Allocation for OFDMA based Overlay Cognitive Radio Networks under Stochastic Rate Constraint
This work presents joint subcarrier, power and bit allocation schemes for multi-user OFDM based overlay cognitive radio under constraints on primary user throughput loss and total secondary user transmitted power. Closed form for expressions for the optimal power and bit allocations are initially derived. Subsequently, optimal and suboptimal algorithms to realise the joint subcarrier, power and...
متن کاملBit-rate Allocation, Scheduling, and Statistical Multiplexing for Wireless Video Streaming
Due to the scarcity of wireless resources, efficient resource allocation is essential to the success of cellular systems. With the proliferation of bandwidth-hungry multimedia applications with diverse traffic characteristics and quality of service requirements, the resource management is becoming particularly challenging. In this thesis, we address some of the key link-layer resource allocatio...
متن کاملBER-based Optimal Power Allocation for Cognitive Relay Networks
In this paper, we consider an optimal power allocation scheme for Rayleigh fading channels in cognitive relay networks considering both total transmit power and average interference power constraints. We derive the optimal power allocation scheme between the cognitive source and relay aiming at minimizing the bit error rate of cognitive system by applying convex optimization method. Simulation ...
متن کاملA Markov Decision Process based flow assignment framework for heterogeneous network access
We consider a scenario where devices with multiple networking capabilities access networks with heterogeneous characteristics. In such a setting, we address the problem of efficient utilization of multiple access networks (wireless and/or wireline) by devices via optimal assignment of traffic flows with given utilities to different networks. We develop and analyze a device middleware functional...
