—Previous work demonstrated that the improvements in spectral efficiency and link reliability can be obtained in wireless relay networks employing terminals with MIMO capability...
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...
For wireless networks with multiple sources, an omnidirectional relay scheme is developed, where each node can help relay multiple messages in different directions. This is accomp...
AbstractWe consider a wireless network consisting of multiple sources communicating with their corresponding destinations utilizing a single half-duplex relay. The goal is to min...
In the multiple-input multiple-output (MIMO) broadcast channel with imperfect channel state information (CSI), neither the capacity nor the optimal transmission technique have been...
