How much Training is Needed in Downlink Cell-Free mMIMO under LoS/NLoS channels?
Sai Manikanta Rishi Rani, Ribhu Chopra, Kumar Appaiah
The assumption that no LoS channels exist between wireless access points~(APs) and user equipments~(UEs) becomes questionable in the context of the recent developments in the direc…
Robust Direction-of-Arrival Estimation using Array Feedback Beamforming in Low SNR Scenarios
Parth Mehta, Kumar Appaiah, Rajbabu Velmurugan
A new spatial IIR beamformer based direction-of-arrival (DoA) estimation method is proposed in this paper. We propose a retransmission based spatial feedback method for an array of…
Granger Causality Detection via Sequential Hypothesis Testing
Rahul Devendra, Ribhu Chopra, Kumar Appaiah
Most of the metrics used for detecting a causal relationship among multiple time series ignore the effects of practical measurement impairments, such as finite sample effects, unde…
Lattice All-Pass Filter based Precoder Adaptation for MIMO Wireless Channels
Parth Mehta, Agulla Surya Bharath, Kumar Appaiah +2
Modern 5G communication systems employ multiple-input multiple-output (MIMO) in conjunction with orthogonal frequency division multiplexing (OFDM) to enhance data rates, particular…
Design of Discrete-time Matrix All-Pass Filters Using Subspace Nevanlinna Pick Interpolation
Agulla Surya Bharath, Devanshu Singh Gaharwar, Kumar Appaiah +1
Unitary matrix-valued functions of frequency are matrix all-pass systems, since they preserve the norm of the input vector signals. Typically, such systems are represented and anal…
An open-source simulation package for power electronics education
Mahesh B. Patil, V. V. S. Pavan Kumar Hari, Ruchita D. Korgaonkar +1
Extension of the open-source simulation package GSEIM for power electronics applications is presented. Recent developments in GSEIM, including those oriented specifically towards p…
