Achievable Throughput of Multi-mode Multiuser MIMO with Imperfect CSI Constraints
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...

Minimizing Transmit Power for Coherent Communications in Wireless Sensor Networks With Finite-Rate Feedback
We minimize average transmit power with finite-rate feedback for coherent communications in a wireless sensor network (WSN), where sensors communicate with a fusion center using ad...

Fundamental Limits in MIMO Broadcast Channels
— This paper studies the fundamental limits of MIMO broadcast channels from a high level, determining the sum-rate capacity of the system as a function of system paramaters, such...

Ergodic and Outage Performance of Fading Broadcast Channels with 1-Bit Feedback
In this paper, the ergodic sum-rate and outage probability of a downlink single-antenna channel with K users are analyzed in the presence of Rayleigh flat fading, where limited cha...

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 ...
