A realistic Multi-Input Multi-Output (MIMO) spatiotemporal radio channel model for simulation of MultiElement Antenna (MEA) systems is presented. The model is based on fundamental theory from ElectroMagnetic (EM) scattering where the properties of the transmit and receive antennas are included. Both the direction and amplitude of the electromagnetic field are included in the model. Furthermore, mutual coupling between the antenna elements is also accounted for since the typical MIMO system most likely will use closely spaced antenna elements. Surprisingly, it is found that mutual coupling actually decorrelates the received signals. Thus, mutual coupling may, contrary to common belief, sometimes increase the communication capacity.read more

Mutual coupling effects on the capacity of multielement antenna systems

TL;DR: The results presented here show, contrary to some earlier claims, that correlation between different channel coefficients as a function of antenna spacing, can in fact decrease when the mutual coupling effect is accounted for.
