Double directional radio propagation measurements and radio channel modelling pertinent to mobile MIMO communications in microcells

Summary, in English

For simulating mobile MIMO performance, local area SNR variations can be reproduced if small-scale fading distributions are known, transmit bandwidths can be chosen appropriately if flat fading bandwidths are known, and, assuming plane waves, spatial covariance functions can be estimated if power-weighted histograms for angles of arrival (AOA) and angles of departure (AOD) are known. This paper reports the results of double directional sounding measurements made in downtown Ottawa to obtain the needed information. Narrowband small scale fading is modelled as Rayleigh or Rician, coherence bandwidths are reported, and an equation is given through which close approximations to experimentally-determined powerweighted AOA and AOD histograms can be reproduced. A recent literature search revealed that such results, all estimated from the same measurements, have not previously been reported.
