UWB Impulse Radio with Triple-Polarization SIMO

Polarized single-input multiple-output (SIMO) arrays can improve system robustness and rate while offering a compact design. We investigate the error performance of Impulse Radio ultrawideband (UWB) systems with multiple- antenna arrays employing polarization orthogonality. Based on indoor channel measurements, we evaluate the improvement in the link reliability due to dual- or triple-polar antenna arrays. Using a two-dimensional combining receiver, it is demonstrated that polarization diversity can be very effective in reducing the overall system complexity, making Impulse Radio implementation practically feasible.
