Distribution of -th Maximum Order Statistics of Independent, & Non-Identical SNR random variables in fading and its applications in
Srinivas Sagar, Athira Subhash, Sheetal Kalyani
This paper employs extreme value theory to establish the asymptotic distribution of the -th maximum order statistics of signal to noise ratio (SNR) for a fading channel wi…
The Rendezvous Between Extreme Value Theory and Next-generation Networks
Srinivas Sagar, Athira Subhash, Chen-Feng Liu +6
Promising technologies such as massive multiple-input and multiple-output, reconfigurable intelligent reflecting surfaces, non-terrestrial networks, millimetre wave communication,…
Instantaneous Channel Oblivious Phase Shift Design for an IRS-Assisted SIMO System with Quantized Phase Shift
Shashank Shekhar, Athira Subhash, Tejesh Kella +1
We design the phase shifts of an intelligent reflecting surface (IRS)-assisted single-input-multiple-output communication system to minimize the outage probability (OP) and to maxi…
Outage Probability Expressions for an IRS-Assisted System with and without Source-Destination Link for the Case of Quantized Phase Shifts in fading
Mavilla Charishma, Athira Subhash, Shashank Shekhar +1
In this work, we study the outage probability (OP) at the destination of an intelligent reflecting surface (IRS) assisted communication system in a fading environment. A prac…
Cooperative relaying in a SWIPT network:Asymptotic analysis using extreme value theory for non-identically distributed RVs
Athira Subhash, Sheetal Kalyani
This paper derives the distribution of the maximum end-to-end (e2e) signal to noise ratio (SNR) in an opportunistic relay selection based cooperative relaying (CR) network having l…
Transmit Power Policy and Ergodic Multicast Rate Analysis of Cognitive Radio Networks in Generalized Fading
Athira Subhash, Muralikrishnan Srinivasan, Sheetal Kalyani +1
This paper determines the optimum secondary user power allocation and ergodic multicast rate of point-to-multipoint communication in a cognitive radio network in the presence of ou…
