In this paper, we investigate various cooperative transmission techniques for hybrid and/or integrated satellite and terrestrial systems, where satellite and terrestrial components cooperates to provide high quality services. It has been reported that cooperative diversity techniques combined with space time and/or error correction coding schemes could provide appreciable diversity and additional...
In this paper, we present a new results on soft MIMO detection for turbo codes. Proper utilization of soft decision information is one of the important factors affecting the performance of turbo codes. If a spatial multiplexing scheme with multiple antennas is used with turbo codes, the output of the detection process should be soft decision information. In this paper, we present various aspects on...
In this paper, we propose an efficient cooperative diversity scheme for mobile satellite multimedia broadcasting systems. The proposed scheme is a transmit diversity technique to adapt different channel environments, and thus we do not need any channel quality information from the return link. In the proposed scheme, we utilize space-time block coding (STBC) and rate compatible turbo codes in order...
In this letter, we propose a quasi-orthogonal spacetime block coding (QO-STBC) scheme with maximum likelihood (ML) decoding via simple linear detection. A conventional QOSTBC scheme can achieve the full rate, but at the cost of decoding complexity and diversity gain. These disadvantages of the conventional QO-STBC scheme are mainly a result of interference terms in the detection matrix. In this letter,...
