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 کاملDesign and Analysis of Pulse-Shaped Space-Time Block Code Based Symbol Timing Recovery Algorithms
A method for the design of low complexity timing error detectors (TEDs) for orthogonal and quasi-orthogonal space-time block coding (OSTBC and QOSTBC) receivers is presented. It is shown that a difference of threshold crossings timing estimate can be obtained for a two-transmit antenna OSTBC receiver in a frequencyflat Rayleigh fading environment. The S-curve of the resulting TED possesses an i...
متن کاملLow-complexity symbol timing error detection for quasi-orthogonal space??time block codes
The author presents the design and analysis of low-complexity symbol timing error detectors (TEDs) for timing synchronisation in quasi-orthogonal space–time block code (QOSTBC) receivers. The estimators operate on data symbols and approximate decision variables, producing timing error measurements which are shown to be robust to channel fading. In evaluating the detector S-curve for the general...
