MIMO Systems, Channel State Information (CSI), Lloyd’s Quantization Algorithm, Differential Feedback, Ergodic Capacity, Water-Filling Precoding, Rayleigh Fading ChannelsAbstract
In this paper we study the relation between the ergodic capacity and feedback interval for a Multiple Input Multiple Output (MIMO) system. Based on this relation an optimal feedback interval is derived for the Rayleigh fading channel. The minimum differential feedback rate is also determined for this system considering the channelestimation error and channel quantization distortion.
