Abstract
Cognitive radio enables opportunistic utilization of under-used spectrum for networks that are overwhelmed. In
Nairobi city, mobile telephony networks are overwhelmed while broadcast TV channels lie idle in some parts. Research in cognitive
radio concentrates on point-to-point communication and successfully conducts transmitter sensing in order to establish spectrum
holes. However, in broadcast communication such as terrestrial TV, transmitter detection is inefficient, as transmitter signals may
be present yet that licensed channel is not tuned-into by TV receivers, rendering those frequencies essentially idle. Our paper
describes an attempt to use a novel remote technique to detect, model and predict which DVB-T2 channels are not tuned-into by
any TV receiver during the worst mobile traffic jam time, within an overwhelmed mobile cell. An MLP that was GA-optimized to
an MSE of 0.0046245 indicated predictability of TV-viewing and predicted Channel 514 MHz as being idle during the 5.00-5.03 pm
jam time slot.
