Statistical modeling and simulation of the RMS delay spread of indoor radio propagation channels

Using a large empirical data base of 12000 impulse response estimates collected in two office buildings the root mean square (rms) delay spread for the individual impulse responses have been calculated and analyzed. Statistical modeling of /spl tau//sub rms/ includes investigation of the local and global distributions, correlations in space, dependence on transmitter-receiver antenna separation, correlations with large scale path losses, and dependence on the dynamic range of measurements. Using the results of the statistical analysis, a simulation model capable of generating a set of /spl tau//sub rms/ values for spatially-adjacent points has been developed.<
