Hybrid RF-FSO Transceiver for Adaptive Real-time Signal Reception and Distribution
Dr Sunday Ekpo, Dr Muhammed Ijaz, Opeyemi Oguntodu
In recent years, there has been tremendous advancement and growth in information and communications technology.
The increase in the use of video-conferencing, high speed Internet, aircraft monitoring, disaster management etc., has
seen bandwidth and capacity requirements increasing exponentially.
The aim of this research is the production of an integrated multichannel adaptive and reconfigurable hybrid RF-free space
transceiver for real-time signal capturing and distribution.
This research work will be targeting 5G frequency band. However, various simulations will be carried out across the
frequency band (C, X, Ku. Ka-band)
The aims include:
1. Design of RF and FSO transmitters and receivers (Transceiver)
2. Modelling of RF and FSO transmitters and receivers (Transceiver)
3. Simulation of RF and FSO transmitters and receivers (Transceiver)
4. Development and prototyping (Fabrication) of an integrated multichannel adaptive and reconfigurable Hybrid
RF-FSO transceiver.
As this is a qualitative research, various software and hardware are used for data collection. MatLab software is used for
generating various signals; Advanced Design System (ADS) will be used to design the RF transceiver. Optism will be used
for the FSO transceiver. Other software used for this research include: Vector Analyser, SystemVue and Hardware include
Integrated RF/microwave-Fibre communication system testbed.
This research will ensure reliable and sustainable real-time acquisition, processing, and transmission of information.
Applications where this research will be used include, aircraft monitoring; capability-based satellite payload
implementation; seamless space-earth connectivity due to high data rate and availability of links; disaster management;
high-definition video imagery. This research work will change lives as it helps to ease and transform the way information
is passed from one media to the other
How to evaluate dancers’ performance? The validation of a jump mat to be used in the field

Jump capability is crucial for dancers, however, when compared to physically active control participants, they do not jump
significantly higher. Jump height can be increased with training, although there is evidence to suggest that dancers do not
undertake sufficient supplementary training, or that the training may be ineffective. For good jump training results, jump
height should be monitored. Force platforms and 3D-analysis are considered to be the gold standard for jump height
measurements, however, they are expensive and their acquisition is not often possible for dance companies. An
alternative is the jump mat that is cheaper, lighter, and considered to be a reliable method(5), despite accuracy levels
being questionable. The aim of this study was to compare data from jump mat with that from force platform and 3Danalysis
in order to validate and calculate its reliability. One participant performed 12 countermovement jumps in each
situation: jump mat+3D-analysis; force platform+3D-analysis, and; jump mat+force platform+3D-analysis. The jump mat
intra and inter reliability between 12 countermovement jumps was found to be very good (CV=2.93% and CV=3.33%,
respectively). The correlation between jump mat and force plate was r 2 =0.76 and the equation to predict force plate height
from jump mat height was found to be y=1.6664x-36.041. The jump mat overestimate the jump height compared to the
3D-analyses in 12.99±0.64cm, (Bland-Altman analysis 95% limits of agreement ranging from 11.72 to 14.26cm). Jump mat
was found to be reliable and valid for field based monitoring of jump height. This may change dancers’ lives, as better
performance could lead to a more successful career.
