A Study on the Capacity of Narrow- and Wideband MIMO Channel Models

This paper deals with the capacity behaviour of narrow- and wideband multi-input multi-output (MIMO) channel models based on the elliptical scattering model. The temporal, spatial and frequency correlation are incorporated in our model. The distribution of the angles of arrival (AOA) seen at the receiver is modelled by the von Mises density. For the capacity study of the wideband MIMO channels, we consider a bandwidth of 10 MHz and 100 MHz. We have investigated the influence of various model parameters on the capacity, such as the angle spread at the receiver, and the mean AOA. In case of narrowband flat fading channels, a new tight upper bound on the $2\times
