Fundamentals Limits Of Communication In Interference Limited Environments
(2017-08-21)
In multiuser wireless communications, interference not only limits the performance of the system, but also allows users to eavesdrop on other users’ messages. Hence, interference management in multiuser wireless communication ...
Spectrum Sensing Techniques For Cognitive Radio Applications
(2017-07-25)
Cognitive Radio (CR) has received tremendous research attention over the past decade, both in the academia and industry, as it is envisioned as a promising solution to the problem of spectrum scarcity. ACR is a device that ...
Finding A Subset Of Non-defective Items From A Large Population : Fundamental Limits And Efficient Algorithms
(2017-07-12)
Consider a large population containing a small number of defective items. A commonly
encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) ...
Delay Differentiation By Balancing Weighted Queue Lengths
(2017-05-04)
Scheduling policies adopted for statistical multiplexing should provide delay differentiation between different traffic classes, where each class represents an aggregate traffic of individual applications having same ...
Low Power And Low Spur Frequency Synthesizer Circuit Techniques For Energy Efficient Wireless Transmitters
(2017-09-07)
There has been a huge rise in interest in the design of energy efficient wireless sensor networks (WSN) and body area networks (BAN) with the advent of many new applications over the last few decades. The number of sensor ...
Minimization Problems Based On A Parametric Family Of Relative Entropies
(2017-08-21)
We study minimization problems with respect to a one-parameter family of generalized relative entropies. These relative entropies, which we call relative -entropies (denoted I (P; Q)), arise as redundancies under mismatched ...
Optimal Amplify-And-Forward Relaying For Cooperative Communications And Underlay Cognitive Radio
(2017-08-21)
Relay-assisted cooperative communication exploits spatial diversity to combat wireless fading, and is an appealing technology for next generation wireless systems. Several relay cooperation protocols have been proposed in ...
On The Best-m Feedback Scheme In OFDM Systems With Correlated Subchannels
(2017-07-07)
Orthogonal frequency division multiplexing (OFDM) in next generation wireless systems provides high downlink data rates by employing frequency-domain scheduling and rate adaptation at the base station (BS). However, in ...
Source And Channel Coding Techniques for The MIMO Reverse-link Channel
(2017-09-28)
In wireless communication systems, the use of multiple antennas, also known as Multiple-Input Multiple-Output(MIMO) communications, is now a widely accepted and important technology for improving their reliability and ...
Joint Estimation of Impairments in MIMO-OFDM Systems
(2017-11-16)
The integration of Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) techniques has become a preferred solution for the high rate wireless technologies due to its high spectral ...
