Abstract :
This paper derives a general upper bound on the degrees of freedom of multipath field based only on angular power spectrum limited measurements. The numerical results demonstrate that the low-order modal concentration of a wave field based on statistical measurement is proportional to richness of multipath of the wave field. This indicates that we can have a more compact dimensionality of a receiver region when the information is limited to the angular power spectrum with richer multipath.
