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…
Differential Transmit Diversity Based on Quasi-Orthogonal Space-Time Block Code
Chau Yuen, Yong Liang Guan, Tjeng Thiang Tjhung
By using joint modulation and customized constellation set, we show that Quasi-Orthogonal Space-Time Block Code (QO-STBC) can be used to form a new differential space-time modulati…
