A NEW APPROACH FOR ESTIMATING INDOOR RADIO PROPAGATION CHARACTERISTICS

In this paper we present a new approach for estimating the propagation characteristics of indoor radio channels. The technique is based on t he use of the principal component analysis and the information theoret ic criterion. It is shown, based on the simulation results, that the n ew technique can be used to overcome difficulties experienced by conve ntional methods and, as a result, is able to produce greater accuracy in its estimates of the channel parameters. We demonstrate the use of this technique by carrying out data analysis using measured indoor rad io channel data.
