MIMO channel characteristics in a small macrocell - Measured at 5.25 GHz and 200 MHz bandwidth

The purpose of this work is to improve the radio channel characterization in macrocellular scenarios. The effort has been put on the wideband and MIMO aspects. Measurements have been performed at two outdoor and three indoor locations at 5.25 GHz with bandwidth of 200 MHz using a vector network analyzer. An optical fiber was used to achieve distances between transmitter and receiver up to 300m. The channel parameters were estimated by means of maximum likelihood estimation, modeling the channel with a set of discrete plane waves. Based on the estimates joint double directional, delay and polarimetric distributions were determined. Moreover, clustering and statistical distribution of path amplitudes were studied.
