Quasi-Orthogonal Space-Time Block Code
Quasi-Orthogonal Space-Time Block Code presents an up-to-date, comprehensive and in-depth discussion of an important emerging class of space-time codes, called the Quasi-Orthogonal STBC (QO-STBC). Used in Multiple-Input Multiple-Output (MIMO) communication systems, they provide transmit diversity with higher code rates than the well-known orthogonal STBC (OSTBC), yet at lower decoding complexit...
متن کاملA quasi-orthogonal space-time block code
It has been shown that a complex orthogonal design that provides full diversity and full transmission rate for a space–time block code is not possible for more than two antennas. Previous attempts have been concentrated in generalizing orthogonal designs which provide space–time block codes with full diversity and a high transmission rate. In this work, we design rate one codes which are quasi-...
متن کاملPower-Balanced Orthogonal Space-Time Block Code
—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 space-time block codes (O-STBC) with favorable practical attributes. We also show that an AOD can be constructed from an Amicable Family (AF), and such a construction is crucial for achieving a power-balanced O-STBC. In additi...
متن کاملCapacity Approaching Super-Orthogonal Space-Time Block Code
This paper introduces a super-orthogonal space-time block code (STBC). The code construction is based on the expansion of orthogonal block code via a unitary matrix transformation. By expanding the orthogonal block code, both the code rate can be increased and the performance improved in terms of Eb/N0, with a moderate increase of the receiver complexity. Exploiting the partial orthogonality of...
متن کاملA Novel Random-Rotation Quasi-Orthogonal Space-Time Block Code
A novel random-rotation quasi-orthogonal spacetime block code(RR-QO-STBC) transmission scheme is proposed. This transmission diversity scheme randomly rotates every information symbol vector, thus the inter-symbol interference between multi-antennas of QO-STBC is randomized and alleviated. Simulation results suggest, in the high SNR scenario, under the ML detection rule, the proposed scheme out...
