A Novel Wideband MIMO Channel Model and Experimental Validation

We present a novel wideband multiple-input, multiple-output (MIMO) channel model, which we refer to as the structured model. The structured model is based on the eigenvalue decomposition (EVD) of the wideband channel correlation matrix. It does not assume the scatterers at the receiver fade independently of those at the transmitter. It also models correlation between delay bins in the power delay profile (PDP). With preliminary data gathered using McMaster's wideband MIMO software defined radio (the WMSDR) in fixed outdoor locations, and Brigham Young University's (BYU) wideband channel sounder in fixed indoor locations, we show good agreement between modeled and measured data. The two platforms used and the environments in which the data were collected were very different. The proposed model performed equally well with both data sets, demonstrating its robustness.
