Channel Training and Estimation for Reconfigurable Intelligent Surfaces: Exposition of Principles, Approaches, and Open Problems
Bharath Shamasundar, Negar Daryanavardan, Aria Nosratinia
Reconfigurable intelligent surfaces (RIS) are passive controllable arrays of small reflectors that direct electromagnetic energy towards or away from the target nodes, thereby allo…
Constellation Design for Media-based Modulation using Block Codes and Squaring Construction
Bharath Shamasundar, A. Chockalingam
Efficient constellation design is important for improving performance in communication systems. The problem of multidimensional constellation design has been studied extensively in…
A DNN Architecture for the Detection of Generalized Spatial Modulation Signals
Bharath Shamasundar, A. Chockalingam
In this letter, we consider the problem of signal detection in generalized spatial modulation (GSM) using deep neural networks (DNN). We propose a novel modularized DNN architectur…
Multidimensional Index Modulation in Wireless Communications
Bharath Shamasundar, Swaroop Jacob, Sandeep Bhat +1
In index modulation schemes, information bits are conveyed through indexing of transmission entities such as antennas, subcarriers, times slots, precoders, subarrays, and radio fre…
Multiuser Media-based Modulation for Massive MIMO Systems
Bharath Shamasundar, A. Chockalingam
In this paper, we consider {\em media-based modulation (MBM)}, an attractive modulation scheme which is getting increased research attention recently, for the uplink of a massive M…
