چکیده مقاله:
The zero-forcing (ZF) and the minimum mean square error (MMSE) linear receivers, due to their simple decoding process are of great interest. This property of linear receivers hasmotivated research to design new space-time block codes (STBCs) based on them. In this paper, we propose a new familyof STBCs, called O-OACs, by combining the orthogonal STBCs (OSTBCs) and the overlapped Alamouti codes (OACs). The OOACs employ the ZF and the MMSE receivers in their decodingprocesses, which benefit from lower complexity in comparison with the maximum likelihood (ML) decoder. The secondadvantage of the O-OACs is that they need less time slots to be constructed when compared with the recently proposed codes,namely the group orthogonal-Toeplitz codes (GOTCs) and the OACs. So this property of the O-OACs is in accordance withreality. And also simulation results demonstrate that the O-OACs outperform the GOTCs and the OACs
