A Study of Full Rate Full Diversity STBC

Gang Chuai

Abstract

Focusing on the case that existing orthogonal space-time block codes(O-STBC)have not achieve full rate,a type of novel transmit matrix for quasi-orthogonal space-time block code(Q-O- STBC)is proposed based on Tarokh's design criterion of space-time code.A full diversity space-time constellation-rotating(A-STCR)block code is obtained through appropriate modulation constellation rotating.It is introduced the encoding structure and decoding principle of A-STCR code.The validity of this coding is proved.The performance merit of A-STCR block codes is confirmed by Matlab simu- lations and compared with other space-time block codes.
