Abstract

In this paper, we compute cross-correlation functions (CCF)s between space-time-frequency (STF) transfer functions of two sub-channels of three-dimensional (3D) outdoor wideband (WB) and ultra-wideband (UWB) multiple-input multiple-output (MIMO) wireless channels. Such a 3D channel modeling is demanding to consider both azimuthal and elevation multipath propagation waveforms. Using the derived CCF and for a multiple-input single-output system (MISO), we calculate coherence bandwidth (CB) and power spectral density (PSD) at mobile station (MS), and in a stationary scenario. Numerical analysis showes that both CB and PSD highly depend the channel bandwidth, while PSD is also influenced by the elevation distribution of multipath waveforms.
