On -rank additive intersection pairs (RAIP) of codes
Sanjit Bhowmick, Kuntal Deka, Sihem Mesnager
This paper introduces and studies \(\ell\)-rank additive intersection pairs (RAIP) of codes over finite fields for a given positive integer \(\ell\). The notion of \(\ell\)-RAIP pr…
Twisted and Twisted Linearized Reed--Solomon Codes, LCD and ACD MDS constructions
Sanjit Bhowmick, Kuntal Deka, Edgar Martínez-Moro
We investigate a natural subfamily of twisted linearized Reed--Solomon (TLRS) codes in the sum-rank metric, where the twist is applied only to the constant term. We establish a sim…
Optimally Deployed Multistatic OTFS-ISAC Design With Kalman-Based Tracking of Targets
Jyotsna Rani, Kuntal Deka, Ganesh Prasad +1
This paper studies orthogonal time-frequency space (OTFS) modulation aided multistatic integrated sensing and communication (ISAC) in vehicular networks, whereby its delay-Doppler…
Hermitian LCD -Quasi Abelian Codes over Finite Chain Rings
Sanjit Bhowmick, Kuntal Deka
This paper introduces a class of Hermitian LCD -quasi-abelian codes over finite fields and presents a comprehensive enumeration of these codes in which relative minimum weights…
Vehicular Multistatic OTFS-ISAC: A Geometry-Aware Deployment and Kalman-Based Tracking
Jyotsna Rani, Kuntal Deka, Ganesh Prasad +1
Integrated sensing and communication (ISAC) is a promising paradigm for next-generation vehicular networks, yet existing orthogonal frequency-division multiplexing (OFDM)-based des…
Trace duality and additive complementary pairs of additive cyclic codes over finite chain rings
Sanjit Bhowmick, Kuntal Deka, Alexandre Fotue Tabue +1
This paper investigates the algebraic structure of additive complementary pairs of cyclic codes over a finite commutative ring. We demonstrate that for every additive complementary…
Joint Optimization of IRS Deployment and Passive Beamforming to Enhance the Received Power
Jyotsna Rani, Deepak Mishra, Ganesh Prasad +3
Intelligent reflecting surface (IRS) has recently emerged as a promising technology for beyond fifth-generation (B5G) and 6G networks conceived from metamaterials that smartly tune…
