Statistical Inter-Floor Radio Channel Model

Abstract

Statistical inter-floor radio channel model is proposed, based on extension of the existing single-floor Saleh–Valenzuela model. Instead of cluster of rays, the term super-cluster is introduced consisting of a group of clusters disposed just like on single-floor channel impulse response. More super-clusters make inter-floor channel impulse response where Poisson distribution controls their number, exponential distribution controls their mutual disposition and one specific statistic distribution controls their amplitudes taken from separate inter-floor UTD path-loss analysis. The model resumes existing internal structure of impulse responses. It is additionally simplified on a way that triple Poisson process becomes a double one. This model became modified version of Saleh–Valenzuela model, suitable for assessment of inter-floor as well as single-floor channel characteristics. The model accuracy is tested with results obtained by VNA measurements. Analysis showed that this new model may be sufficiently accurate tool for simulation of single-floor and inter-floor channels but acting as a single model. It is necessary just to change average number of clusters which makes difference between the models, this procedure even has a physical sense.
