ABSTRACT
Accurate
path loss modelling and prediction will provide realistic information on the
level of signal attenuation in a service area and contribute positively to a
better performance of cellular radio frequency network. A better predictive
path loss model that will facilitate superb cellular network planning process
will be of great value to cellular radio network planners, stakeholders and end
users. In this study, the development of a model that identifies path loss in a
channel ofmobile cellular network was undertaken for Uyo capital city in Akwa
Ibom State, Nigeria. The adaptive hybrid model which combines multi-resolution
Discrete Wavelet Transform (MDWT) and Long Short Term Memory (LSTM) Recurrent
Neural Network in MATLAB platform was used for modelling and prediction of the
signal coverage path loss in Uyo capital city. Field drive test based
experimental set up with the combination of test mobile system technology, map
info.pro.software and Global positioning system aided the measurement of
Reference Signal Received Power (RSRP) with respect to distance around four
long Term Evolution (LTE) eNode B antenna sites, all which operates at 10MHz
band width across Uyo city. The measured signal data was routed through a wavelet
based decomposition process with three decomposition levels. The decomposed
measured signal data was converted into path loss values and then utilized as
input data to long short term memory model where relevant extracted information
were captured and trained for robust predictive adaptive learning and
prediction. The predicted outcome of the hybrid model was compared to the
conventional prediction models. Some essential performance evaluation indices
were employed for accuracy evaluation and validation of the result obtained.
The result obtained in terms of the hybrid (MDWT-LSTMRNN) approach improves the
mean prediction efficiency by 50% and trains with less time
