Cooperative MAC for Rate Adaptive Randomized Distributed Space-Time Coding
—In a distributed wireless network, it is possible to employ several relays and mimic a multiple antenna transmission system. In this paper we propose a MAC layer solution that a...

Limited feedback for multi-antenna multi-user communications with Generalized Multi-Unitary Decomposition
– In this paper, we propose a decomposition method called Generalized Multi-Unitary Decomposition (GMUD) which is useful in multi-user MIMO precoding. This decomposition transfor...

Uplink-Downlink Duality in Normalized MSE or SINR Under Imperfect Channel Knowledge
Abstract— Duality between the multi-antenna multi-user uplink and the downlink has been discovered in terms of sum rate, capacity region, signal-to-interference-plus-noise-ratio ...
