Abstract

In this paper, we first derive a lower bound for the capacity of MIMO system employing dual-polarization diversity. An upper bound is also derived in the high SNR regime. In a second part, the tightness and validity of the bounds are analyzed by a definition named pseudo condition number. We conclude that the correlation matrices of antenna array have a great impact on the tightness of bounds. The impact of polarization diversity on the capacity and the robustness of MIMO system are analyzed at last.
