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…
Bi-Directional Multi-Antenna Relay Communications with Wireless Network Coding
Chau Yuen, Woon Hau Chin, Yong Liang Guan +2
In this paper, we consider a two-way or bidirectional communications system with a relay equipped with multiple antennas. We show that when the downlink channel state information i…
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…
On the Search for High-Rate Quasi-Orthogonal Space-Time Block Code
Chau Yuen, Yong Liang Guan, Tjeng Thiang Tjhung
A Quasi-Orthogonal Space-Time Block Code (QO-STBC) is attractive because it achieves higher code rate than Orthogonal STBC and lower decoding complexity than nonorthogonal STBC. In…
Optimizing Quasi-Orthogonal STBC Through Group-Constrained Linear Transformation
Chau Yuen, Yong Liang Guan, Tjeng Thiang Tjhung
In this paper, we first derive the generic algebraic structure of a Quasi-Orthogonal STBC (QO-STBC). Next we propose Group-Constrained Linear Transformation (GCLT) as a means to op…
Power-Balanced Orthogonal Space-Time Block Code
Chau Yuen, Yong Liang Guan, Tjeng Thiang Tjhung
In this paper, we propose two new systematic ways to construct amicable orthogonal designs (AOD), with an aim to facilitate the construction of power-balanced orthogonal spacetime…
