Noncoherent space-time block coded modulation
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004Unitary space-time modulation is well tailored for flat fading channels where the noncoherent receiver is used. In this paper, we propose a novel scheme of unitary space-time modulation, called noncoherent space-time block coded modulation, by using the set partitioning of signal sets and multilevel coding.

Equivalent codes and optimality of orthogonal space-time block codes
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011An equivalent model of a multiple-input multiple-output (MIMO) communication system with orthogonal space-time block coding (OSTBC) is proposed based on a newly found connection between OSTBCs and Euclidian codes. A new asymptotic upper bound on the symbol error rate (SER) of OSTBC, which is based on distance spectra of the introduced equivalent ...

PARAFAC2 Receivers for Orthogonal Space-Time Block Codes
2009 IEEE International Conference on Communications, 2009Space-Time Block Codes can be represented by tensors, like for example the Kathri-Rao Space Time codes introduced by Sidiropoulos. In this paper, we introduce a Parallel Factor Analysis 2 (PARAFAC2) model for Orthogonal Space-Time Block Codes (OSTBC). This model, along with tensor diagonalisation designed for orthogonal tensors, leads us to develop a ...

Space-Time Block Coding for Wireless Communications
2003Space-time coding is a technique that promises greatly improved performance in wireless networks by using multiple antennas at the transmitter and receiver. Space-Time Block Coding for Wireless Communications, first published in 2003, is an introduction to the theory of this technology.

High-Rate Space-Time Block Coding Schemes
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008A rate-6/4 full-diversity orthogonal space-time block code (STBC) is constructed for QPSK and 2 transmit antennas by applying constellation scaling and rotation to the set of quaternions used in Alamouti code. Also given is a rate-9/8 full-diversity quasi-orthogonal space-time block code (QOSTBC) for 4 transmit antennas.

A quasi-orthogonal space-time block code
2000 IEEE Wireless Communications and Networking Conference. Conference Record (Cat. No.00TH8540), 2001Summary: 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.

Space time block codes with turbo codes
2011This paper aims to provide efficient solutions to improve the power efficiency, like implementation of schemes using MIMO (Multiple-Input Multiple-Output), with error correction codes. Thanks to the union of these two techniques is possible to obtain a low error probability with low power consumption. This paper shows STBC (Space Time Block Codes) with
