— MIMO system design for real applications requires that factors such as channel estimation errors, feedback quan-tisation and realistic channel responses be taken into account. Limited feedback precoding has been introduced to address the feedback overhead; it is a quantised approximation to equal-power eigenbeamforming. The performance of this technique(More)
—This paper presents a technique for assigning binary labels to the points in an arbitrary Grassmannian constellation in a manner that approximates the Gray labelling. The idea behind this technique is to match the Grassmannian constellation of interest to the points in an auxiliary constellation that can be readily Gray labelled. In order to demonstrate(More)
