Joint Power-control and Antenna Selection in User-Centric Cell-Free Systems with Mixed Resolution ADC
Shashank Shekhar, Athira Subhash, Muralikrishnan Srinivasan +1
In this paper, we propose a scheme for the joint optimization of the user transmit power and the antenna selection at the access points (AP)s of a user-centric cell-free massive mu…
How to boost autoencoders?
Sai Krishna, Thulasi Tholeti, Sheetal Kalyani
Autoencoders are a category of neural networks with applications in numerous domains and hence, improvement of their performance is gaining substantial interest from the machine le…
BayesAoA: A Bayesian method for Computation Efficient Angle of Arrival Estimation
Akshay Sharma, Nancy Nayak, Sheetal Kalyani
The angle of Arrival (AoA) estimation is of great interest in modern communication systems. Traditional maximum likelihood-based iterative algorithms are sensitive to initializatio…
Binarized ResNet: Enabling Robust Automatic Modulation Classification at the resource-constrained Edge
Deepsayan Sadhukhan, Nitin Priyadarshini Shankar, Nancy Nayak +2
Recently, deep neural networks (DNNs) have been used extensively for automatic modulation classification (AMC), and the results have been quite promising. However, DNNs have high m…
Realizing Neural Decoder at the Edge with Ensembled BNN
Devannagari Vikas, Nancy Nayak, Sheetal Kalyani
In this work, we propose extreme compression techniques like binarization, ternarization for Neural Decoders such as TurboAE. These methods reduce memory and computation by a facto…
Deep learned SVT: Unrolling singular value thresholding to obtain better MSE
Siva Shanmugam, Sheetal Kalyani
Affine rank minimization problem is the generalized version of low rank matrix completion problem where linear combinations of the entries of a low rank matrix are observed and the…
Cooperative 3D Beamforming for Small-Cell and Cell-Free 6G Systems
Sarath Gopi, Sheetal Kalyani, Lajos Hanzo
Three dimensional (3D) resource reuse is an important design requirement for the prospective 6G wireless communication systems. Hence, we propose a cooperative 3D beamformer for us…
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…
On the Differentially Private Nature of Perturbed Gradient Descent
Thulasi Tholeti, Sheetal Kalyani
We consider the problem of empirical risk minimization given a database, using the gradient descent algorithm. We note that the function to be optimized may be non-convex, consisti…
Outage Probability Analysis of Uplink Cell-Free Massive MIMO Network with and without Pilot Contamination
Shashank Shekhar, Muralikrishnan Srinivasan, Sheetal Kalyani +1
This paper derives approximate outage probability (OP) expressions for uplink cell-free massive multiple-input-multiple-output (CF-mMIMO) systems with and without pilot contaminati…
On the Asymptotic Performance Analysis of the k-th Best Link Selection over Non-identical Non-central Chi-square Fading Channels
Athira Subhash, Sheetal Kalyani, Yazan H. Al-Badarneh +1
This paper derives the asymptotic distribution of the normalized -th maximum order statistics of a sequence of non-central chi-square random variables with non-identical non-cen…
