Abstract
Several adaptive techniques are described to combat interference in multiple-input multiple-output (MIMO) systems. In addition to adaptive frequency selection, interference suppression techniques for a selected carrier frequency are presented. The interference suppression technique can be adaptively selected based on the availability and quality of channel state information (CSI) and interference statistics. Techniques to estimate interference statistics are also presented. Interference mitigation techniques are also presented for automatic gain control (AGC), intermittent interference, and interference caused to other networks.
