Limited feedback achieves the empirical capacity
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boo...

On the Statistics and MAC Implications of Channel Estimation Errors in MIMO Ad Hoc Networks
—In this paper, we propose an analytical technique to evaluate the statistics of the channel estimation error in a simple multi-user ad hoc networking scenario. This problem is v...
