Artificial neural network based simulation of correlated short-term fading

This paper presents a novel method for simulation of two correlated short-term fading envelopes in mobile radio channel. Proposed method is enabled by artificial neural network principles. The main idea was to base the simulation approach solely on the measurement results. In order to obtain an adequate measured data set, extensive electric field strength measurements were carried out in an indoor environment, in a nonline-of-sight scenario. For verification of the proposed method, performance comparisons were made against the contemporary coloring matrix based method. According to comprehensive quantitative and qualitative statistical analysis it seems that the proposed method is in better agreement with the short-term fading phenomenon experienced in real propagation environment.
