Optimal Power Allocation in Downlink Multicarrier NOMA Systems: Theory and Fast Algorithms
Sepehr Rezvani, Eduard A. Jorswieck, Roghayeh Joda +1
In this work, we address the problem of finding globally optimal power allocation strategies to maximize the users sum-rate (SR) as well as system energy efficiency (EE) in the dow…
Delay-Distortion-Power Trade Offs in Quasi-Stationary Source Transmission over Block Fading Channels
Roghayeh Joda, Farshad Lahouti, Elza Erkip
This paper investigates delay-distortion-power trade offs in transmission of quasi-stationary sources over block fading channels by studying encoder and decoder buffering technique…
Access Policy Design for Cognitive Secondary Users under a Primary Type-I HARQ Process
Roghayeh Joda, Michele Zorzi
In this paper, an underlay cognitive radio network that consists of an arbitrary number of secondary users (SU) is considered, in which the primary user (PU) employs Type-I Hybrid…
Delay-limited Source and Channel Coding of Quasi-Stationary Sources over Block Fading Channels: Design and Scaling Laws
Roghayeh Joda, Farshad Lahouti
In this paper, delay-limited transmission of quasi-stationary sources over block fading channels are considered. Considering distortion outage probability as the performance measur…
Network Code Design for Orthogonal Two-hop Network with Broadcasting Relay: A Joint Source-Channel-Network Coding Approach
Roghayeh Joda, Farshad Lahouti
This paper addresses network code design for robust transmission of sources over an orthogonal two-hop wireless network with a broadcasting relay. The network consists of multiple…
