A vector-perturbation technique for near-capacity multiantenna multiuser communication-part I: channel inversion and regularization
TL;DR: A simple encoding algorithm is introduced that achieves near-capacity at sum rates of tens of bits/channel use and regularization is introduced to improve the condition of the inverse and maximize the signal-to-interference-plus-noise ratio at the receivers.
Journal ArticleDOI
A vector-perturbation technique for near-capacity multiantenna multiuser communication-part II: perturbation
TL;DR: A simple encoding algorithm is introduced that achieves near-capacity at sum-rates of tens of bits/channel use and a certain perturbation of the data using a "sphere encoder" can be chosen to further reduce the energy of the transmitted signal.
Journal ArticleDOI
Effective SNR for space-time modulation over a time-varying Rician channel
TL;DR: This letter examines the performance degradation that results when time-varying flat fading is encountered when using trained and unitary space-time modulation.
Proceedings ArticleDOI
Downlink transmit beamforming in multi-user MIMO systems
TL;DR: This paper compares the various goals of the above algorithms, and detail their respective advantages and disadvantages in terms of computational complexity, required transmit power, network throughput, and assumed receiver capabilities.

TL;DR: This chapter considers the multi-user downlink, where a base station with multiple antennas transmits simultaneously to more than one user, and compares the number of simultaneous users the channel will support for the two different environments, the amount of separation of the users necessary to achieve maximum throughput, and the quality of channel information available to the base station when the users are mobile.
