Rate-Splitting--Inspired Bistatic OFDM-ISAC
Bruno F. Costa, Anup Mishra, Israel Leyva-Mayorga +2
Achieving effective uplink bistatic ISAC over an OFDM waveform gives rise to challenging interference structures. These are mostly due to unequal direct- and echo-path contribution…
Tunable Gaussian Pulse for Delay-Doppler ISAC
Bruno Felipe Costa, Anup Mishra, Israel Leyva-Mayorga +2
Integrated sensing and communication (ISAC) for next-generation networks targets robust operation under high mobility and high Doppler spread, leading to severe inter-carrier inter…
Derivation of CRB and Refined SINR Expressions for OTFS-RSMA LEO ISAC Systems
Bruno Felipe Costa, Taufik Abrão
This document provides detailed step-by-step derivations for the Cramér-Rao Bounds (CRB) for sensing parameters and the refined Signal-to-Interference-plus-Noise Ratio (SINR) expre…
Refined Metrics, Sensing Limits, and Resource Allocation in OTFS-RSMA LEO ISAC
Bruno Felipe Costa, Taufik Abrão
This paper develops an integrated OTFS-RSMA framework employing advanced SP techniques tailored for this demanding environment. We derive refined communication performance metrics,…
GA-Aided Directivity in Volumetric and Planar Massive-Antenna Array Design
Bruno Felipe Costa, Taufik Abrão
The problem of directivity enhancement, leading to the increase in the directivity gain over a certain desired angle of arrival/departure (AoA/AoD), is considered in this work. A n…
Closed-Form Directivity Expression for Arbitrary Volumetric Antenna Arrays
Bruno Felipe Costa, Taufik Abrao
It is proposed a closed-form expression of directivity for an arbitrary volumetric antenna arrays using a general element pattern expression of type , with…
