Error correction method using neural network trained by measurement data in ray-tracing propagation prediction
Junpei Mizuno, Tetsuro Imai (NTT DOCOMO) AP2008-157
Abstract (in Japanese) (See Japanese page) 
(in English) Ray-tracing method can predict site-specifically propagation characteristics based on theory of geometrical optics with considering peripheral buildings. But, there is an error between predictions and measurement results because of imperfect building database, and so on. In this paper, we propose a method reducing the error using neural-network trained by measurement result, and evaluate the effect.
