Abstract
Accurate modeling of indoor multiple-input multiple-output (MIMO) channels is an important prerequisite for multi-antenna system design. In this paper, a new model for indoor MIMO channels is proposed, and a closed-form expression for the spatio-temporal cross-correlation function between any two subchannels is derived. This new analytical correlation expression includes many key physical parameters of interest such as mean angle-of-departure at the transmitter and mean angle-of-arrival at the receiver, the associated angle spreads, the distance between transmitter and receiver, etc. in a compact form. Comparison of this model with channel correlations and capacity, using the collected indoor MIMO data, exhibits the utility of the model.
