WLC38-5: Multi-Antenna Limited Feedback for Temporally-Correlated Channels: Feedback Compression

Abstract

A novel method is proposed for reducing the feedback rate of a transmit beamforming system with feedback of quantized channel state information. Specifically, the channel is modeled as a Markov chain and the feedback bits are compressed by truncating the Markov chain transition probabilities. Using the proposed method, the feedback rate can be compressed by… (More)
