A Ray Launching Method For The Prediction Of Indoor Radio Channel Characteristics

Abstract

Presented here is an analytical method for the prediction of power delay profiles within a room environment. The model works directly on a 3-D description of a room. Provided here is a brief discussion of the model and a presentation of both measured and modelled results for delay spread values, which are shown to be in good agreement. The model’s output for narrowband signal strength values was found to be well represented by the usual theoretical distributions.
