Speech systems for autonomous unmanned aircraft: enabling autonomous unmanned aircraft to communicate in civil airspace

Author: Burger, Chris R ; Barnard, E ; Jones, T Date: Sep 2011 Airspace control is currently based largely on the exchange of speech between aircraft and Air Traffic Service Units, or between aircraft themselves. ICAO regulatory guidelines make no distinction between unmanned and manned aircraft, implying ... Read more
Testing performance for several use cases with an indoor OpenAirInterface USRP-Based base station

Author: Dludla, Angeline G ; Vilakazi, Mlamuli C ; Burger, Chris R ; Lysko, Albert A ; Ngcama, Lwando ; Mboweni, Lawrence ; Masonta, Moshe ; Kobo, Hlabishi I ; Mamushiane, Lusani Date: Nov 2022 This paper presents the early phases of the implementation of a Radio Access Network (RAN) based on OpenAirInterface (OAI) for a fifth-generation (5G) mobile network. Because the availability of full OAI 5G support was delayed, we initially ... Read more
Towards the certification of non-deterministic control systems for safety-critical applications: analysing aviation analogies for possible certification strategies

Author: Burger, Chris R ; Jones, T Date: Nov 2011 Current certification criteria for safety-critical systems exclude non-deterministic control systems.
