A Lattice-Based MIMO Broadcast Precoder with Block Diagonalization for Multi-Stream Transmission
Abstract— Precoding with block diagonalization is an attractive approach for approaching sum capacity in multiuser MIMO (multiple input multiple output) broadcast channels. This ...

Decentralized Base Station Processing for Multiuser MIMO Downlink CoMP
—Coordinated multi-point transmission/reception (CoMP), in which base stations (BSs) cooperate during the downlink, has been identified as a tool for improving user rates and mi...

Linear Processing and Sum Throughput in the Multiuser MIMO Downlink
We consider linear precoding and decoding in the downlink of a multiuser multiple-input, multipleoutput (MIMO) system, wherein each user may receive more than one data stream. We ...

Optimization of Training and Scheduling in the Non-Coherent SIMO Multiple Access Channel
— Channel state information (CSI) is important for achieving large rates in MIMO channels. However, in timevarying MIMO channels, there is a tradeoff between the time/energy spen...

Downlink MIMO Systems Using Cooperation Among Base Stations in a Slow Fading Channel
To increase the achievable sum rate of downlink MIMO (Multiple Input Multiple Output) systems, the cooperation among Base Stations (BS) is investigated in a slow fading channel. Th...
