A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...

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...

Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...

Effects of cooperation on the secrecy of multiple access channels with generalized feedback
—We investigate the effects of user cooperation on the secrecy of multiple access channels with generalized feedback (MAC-GF). We show that cooperation can increase the achievabl...
