Design and Implementation of Low Complexity Reconfigurable Filtered-OFDM based LDACS
N. Agrawal, A. Ambede, S. J. Darak +2
L-band Digital Aeronautical Communication System (LDACS) aims to exploit vacant spectrum in L-band via spectrum sharing, and orthogonal frequency division multiplexing (OFDM) is th…
Spectral Coexistence of LDACS and DME: Analysis via Hardware Software Co-Design in Presence of Real Channels and RF Impairments
Niharika Agrawal, S. J. Darak, Faouzi Bader
To meet the exponentially increasing air traffic, L-band (960-1164 MHz) digital aeronautical communication system (LDACS) has been introduced. The LDACS aims to exploit the vacant…
New Reconfigurable L-Band Digital Aeronautical Communication System
Niharika Agrawal
To meet an ever-increasing demand of the spectrum for communication between aircraft and ground terminals, orthogonal frequency division multiplexing (OFDM) based L-band (960-1164M…
Variable Cutoff Frequency FIR Filters: A Survey
Sumedh Dhabu, Abhishek Ambede, Smitha K. G. +2
Many signal processing applications require digital filters with variable frequency characteristics, especially the filters with variable bandwidth. Due to their linear phase and i…
