Abstract :
Generalising previous results for narrowband multiple-antenna channels, a quadratic growth in multipath with the array size is reported for ultra-wideband indoor channels, based on experimental analysis. It is shown that the observed increase in multipath is sufficient to guarantee multiple-antenna capacity growth linearly with the array size, facilitating multi-gigabit future wireless systems.
