Noncoherent space-time block coded modulation

2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004
Unitary 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.

High-Rate Space-Time Block Coding Schemes

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008
A 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), 2001
Summary: 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

2011
This 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
