QAM Codebooks for Low-Complexity Limited Feedback MIMO Beamforming
— This paper proposes a new QAM based codebook for beamforming in multiple-input multiple-output (MIMO) wireless systems with a limited-rate feedback channel. We show that such c...

Multi-User Diversity vs. Accurate Channel Feedback for MIMO Broadcast Channels
— A multiple transmit antenna, single receive antenna (per receiver) downlink channel with limited channel feedback is considered. Given a constraint on the total system-wide cha...

Optimal Precoder for Rate 1 Space-Time Block Codes
Abstract— Despite primary space-time coding where the channel state information (CSI) is available at the receiver only, the capacity and performance of multiple-input multiple-o...

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...
