Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

People and Nature, Volume 8, Issue 5, Page 1419-1436, May 2026.Abstract Understanding how local communities perceive and prioritise ecosystem services (ES) across diverse ecological contexts is essential for improving protected area (PA) management. However, most studies focus on single ecosystems and lack cross‐ecological comparisons. This study aimed to explore how communities living in and around PAs in Ghana's

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.
