Signal Processing, Networks and Systems

The Signal Processing, Networks, and Systems (SPNS) research group was initiated
in 2018 under the Department of Electrical, Computer and Telecommunications
Engineering. The research group aims to focus on the development of fundamental
theories, algorithms and systems for wireless communication networks.
Research Areas
 Antenna theory and design
 Wireless transmission techniques
 Nanosatellite Technologies
 Machine Type Communication
 Ultra-Reliable Low-Latency Communication (URLLC)
 Ultra-Dense Heterogenous Networks
Previous Research Projects
 NOMA, Auction and Blockchain Applications in Wireless Networks with
Loughborough University.
 African Constellation Satellite Network (AFCONSAT) – Constellation for
African Small Satellites

Current Research Activities
 Design and Implementation of an Attitude Determination System for 1U
CubeSat.
 Design of a Phased Array Antenna for 5G Wireless Applications
 Integration of mMTC and LEO satellite constellations for Massive Connectivity
and Ubiquitous Coverage.
 Design and Implementation of a Digital Front-End for 1U CubeSat Software
Defined Radio.
 Design and Implementation of an Attitude Control System for a 1U CubeSat
 Design and Implementation of a Multi-band Antenna Array for CubeSat
Application.
 Design and Implementation of a Reconfigurable Metasurface Antenna.
 Design and Implementation of Passive Bistatic Radar for Low Altitude Targets
