TL;DR: A 3D-structured orthogonal matching pursuit algorithm based channel estimation technique to solve the downlink channel estimation problem for OTFS massive MIMO.

TL;DR: In this paper, a generalized orthogonal/non-orthogonal random access scheme was proposed to improve the network efficiency while reducing the signaling overhead in the UDHN.

TL;DR: By utilizing the time difference of arrival (TDOA) of a signal received at spatially separated sensors, a novel algorithm for source location is proposed that gives sufficient accuracy with lower computational cost, and is more robust to large measurement noise than the compared algorithms.

TL;DR: This work conceive wideband channel estimation for IRS-aided communication systems by explicitly taking the effect of beam squint into consideration, and proposes a bespoke pilot design by exploiting the specific the characteristics of the mutual correlation function and cross-entropy theory for achieving an improved channel estimation performance.

TL;DR: In this paper, the authors studied the resource allocation and trajectory design for secure UAV-enabled communication systems, where multiple multi-purpose UAV base stations are dispatched to provide secure communications to multiple legitimate ground users (GUs) in the existence of multiple eavesdroppers (Eves).
