A system and method for predicting the location of a transmitter in an
indoor zone of interest, including fixed receiver for receiving a signal
from the transmitter, the receiver deriving a fingerprint from the
received signal, and a trained neural network. The trained neural network
predicts the transmitter location from the fingerprint. The method
includes receiving a signal transmitted from the transmitter at a
fixed-location receiver, deriving a fingerprint from the received signal,
supplying the fingerprint to a trained neural network, and reading the
predicted location from the neural network. The artificial neural network
may further be trained and include a plurality of weights and biases is
also shown. The method may include collecting a training data set of
fingerprints and corresponding locations, inputting the training data set
to the neural network, and adjusting the weights and biases by minimizing
a sum of squares error function.
