A Continuous Vector-Perturbation for Multi-Antenna Multi-User Communication
Wee Seng Chua, Chau Yuen, Francois Chin
The sum-rate of the broadcast channel in a multi-antenna multi-user communication system can be achieved by using precoding and adding a regular perturbation to the data vector. Th…

Limited Feedback for Multi-Antenna Multi-user Communications with Generalized Multi-Unitary Decomposition
Wee Seng Chua, Chau Yuen, Yong Liang Guan +1
In this paper, we propose a decomposition method called Generalized Multi-Unitary Decomposition (GMUD) which is useful in multi-user MIMO precoding. This decomposition transforms a…
