Abstract

The frequency-selective radio-wave propagation characteristics for in-house communication systems are statistically characterized for the cases of line-of-sight and obstructed path propagation. Using the theory of random time-variant linear filters, it is found that the RMS (root mean square) delay spread, the Doppler spread and coherence time, the coherence bandwidth, and the total received power are well suited to describe the wideband characteristics of inhouse communication channels. The mean delay, the RMS delay spread, the coherence bandwidth and the echo profile width were measured and used as design parameters for wideband communication systems and for predicting some limits of performance of conventional narrowband analog and digital communication systems
