Multi-User SISO Precoding based on Generalized Multi-Unitary Decomposition for Single-carrier Transmission in Frequency Selective Channel
Wee Seng Chua, Chau Yuen, Yong Liang Guan +1
In this paper, we propose to exploit the richly scattered multi-path nature of a frequency selective channel to provide additional degrees of freedom for desigining effective preco…

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…
