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…
