Throughput Maximization in Multi-Channel Cognitive Radio Systems with Delay Constraints
Ahmed Ewaisha, Cihan Tepedelenlioglu
We study the throughput-vs-delay trade-off in an overlay multi-channel single-secondary-user cognitive radio system. Due to the limited sensing capabilities of the cognitive radio…
Delay Optimal Joint Scheduling-and-Power-Control for Cognitive Radio Uplinks
Ahmed Ewaisha, Cihan Tepedelenlioglu
An uplink cognitive radio system with a single primary user (PU) and multiple secondary users (SUs) is considered. The SUs have an individual average delay constraint and an aggreg…
Delay-Optimal Scheduling and Power Control for Instantaneous-Interference-Limited CRs
Ahmed Ewaisha, Cihan Tepedelenlioglu
We study an uplink multi secondary user (SU) cognitive radio system suffering statistical heterogeneity among SUs' channels. This heterogeneity may result in differentiated delay p…
Dynamic Scheduling for Delay Guarantees for Heterogeneous Cognitive Radio Users
Ahmed Ewaisha, Cihan Tepedelenlioglu
We study an uplink multi secondary user (SU) system having statistical delay constraints, and an average interference constraint to the primary user (PU). SUs with heterogeneous in…
A New Representation for the Symbol Error Rate
Adithya Rajan, Cihan Tepedelenlioglu
The symbol error rate of the minimum distance detector for an arbitrary multi-dimensional constellation impaired by additive white Gaussian noise is characterized as the product of…
Stochastic Ordering of Interferences in Large-scale Wireless Networks
Junghoon Lee, Cihan Tepedelenlioglu
Stochastic orders are binary relations defined on probability distributions which capture intuitive notions like being larger or being more variable. This paper introduces stochast…
