Energy-Efficient THz Sensing with Hybrid THz/VLC Communication Under Human Blockage Effects
Hanshita Prabhakar, Neetu R. R., Vivek Ashok Bohara
This paper presents an energy-efficient indoor system integrating \ac{THz} with \ac{VLC}. \ac{THz} communication offers ultra-high-capacity links but is limited by severe path loss…
UAV-Based Cell-Free Massive MIMO: Joint Placement and Power Optimization under Fronthaul Capacity Limitations
Neetu R. R, Ozan Alp Topal, Özlem Tuğfe Demir +4
We consider a cell-free massive multiple-input multiple-output (mMIMO) network, where unmanned aerial vehicles (UAVs) equipped with multiple antennas serve as distributed UAV-acces…
Handover_Management_in_UAV_Networks_with_Blockages
Neetu R R, Gourab Ghatak, Vivek Ashok Bohara
We investigate the performance of unmanned aerial vehicle (UAV)-based networks in urban environments characterized by blockages, focusing on their capability to support the service…
Towards 6G-V2X: Aggregated RF-VLC for Ultra-Reliable and Low-Latency Autonomous Driving
Gurinder Singh, Anand Srivastava, Vivek Ashok Bohara +3
We are witnessing a transition to a new era where driverless cars will be pervasively connected to deliver significantly improved safety, traffic efficiency, and travel experiences…
A Tutorial on Decoding Techniques of Sparse Code Multiple Access
Saumya Chaturvedi, Zilong Liu, Vivek Ashok Bohara +2
Sparse Code Multiple Access (SCMA) is a disruptive code-domain non-orthogonal multiple access (NOMA) scheme to enable \color{black}future massive machine-type communication network…
Low-Complexity Codebook Design for SCMA based Visible Light Communication
Saumya Chaturvedi, Dil Nashin Anwar, Vivek Ashok Bohara +2
Sparse code multiple access (SCMA), as a code-domain non-orthogonal multiple access (NOMA) scheme, has received considerable research attention for enabling massive connectivity in…
eSampling: Energy Harvesting ADCs
Neha Jain, Nir Shlezinger, Bhawna Tiwari +4
Analog-to-digital converters (ADCs) allow physical signals to be processed using digital hardware. The power consumed in conversion grows with the sampling rate and quantization re…
eSampling: Rethinking Sampling with Energy Harvesting
Neha Jain, Bhawna Tiwari, Anubha Gupta +2
In general, real world signals are analog in nature. To capture these signals for further processing, or transmission, signals are converted into digital bits using analog-to-digit…
PCI-MDR: Missing Data Recovery in Wireless Sensor Networks using Partial Canonical Identity Matrix
Neha Jain, Anubha Gupta, Vivek Ashok Bohara
Data loss in wireless sensor networks (WSNs) is quite prevalent. Since sensor nodes are employed for various critical applications, accurate recovery of missing data is important.…
