Cur rent state-of-the-art receiver algorithms face challenges, including delays, error propagation, and poor performance at low SNR levels. To address these issues, this paper introduces a novel re ceiver design leveraging improved correlation properties of new pilot sequences. The proposed design performs CSI estimation at the pilot detection stage, thus eliminating iterative processes, mitigating long synchronization times, and enhancing receiver performance at lower SNR levels. 2025-10-01T00:00:00Z http://hdl.handle.net/10150/679599 Telemetry Spectrum Encroachment Review of Related WRC-27 Agenda and Domestic Threats Chalfant, Tim; Williams, Guy A review of international and domestic spectrum issues that present challenges for the future use of radio frequency telemetry after the 2023 World Radiocommunications Conference (WRC-23). Several agenda items addressed there have a potential for telemetry spectrum encroachment and are presented in this paper. Agenda topics of telemetry interest in future World Radiocommunications Conferences (WRCs), in particular several agenda items that will be considered at the 2027 World Radiocommunications Conference (WRC-27), are a particular focus. International telemetry vendors, suppliers, and users need to be aware of, and potentially engage with, their national administrations on these items to protect and preserve spectrum for the future of aeronautical mobile telemetry. 2025-10-01T00:00:00Z
