Space-time block coding for spatial modulation

open access: yes21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
Space-time block coded spatial modulation (STBC-SM), which employs space-time block coding (STBC) for spatial modulation (SM), is proposed as a new multiple-input multiple-output (MIMO) transmission scheme. In the STBC-SM scheme, the transmitted information symbols are expanded not only to the space and time domains but also to the spatial (antenna ...

L2 Orthogonal Space Time Code for Continuous Phase Modulation [PDF]

open access: yes, 2008
To combine the high power efficiency of Continuous Phase Modulation (CPM) with either high spectral efficiency or enhanced performance in low Signal to Noise conditions, some authors have proposed to introduce CPM in a MIMO frame, by using Space Time ...

A Rotated Quasi-Orthogonal Space-Time Block Code for Asynchronous Cooperative Diversity

open access: yesEntropy, 2012
The rotated quasi-orthogonal space-time block code (RQSTBC) for asynchronous cooperative diversity is proposed in this paper. The source selects half of the symbols from a signal constellation set and the other half of them from that constellation ...

Space-Time Trellis and Space-Time Block Coding Versus Adaptive Modulation and Coding Aided OFDM for Wideband Channels

open access: yes, 2006
—The achievable performance of channel coded spacetime trellis (STT) codes and space-time block (STB) codes transmitted over wideband channels is studied in the context of schemes having an effective throughput of 2 bits/symbol (BPS) and 3 BPS.

Code diversity in multiple antenna wireless communication

open access: yes, 2008
The standard approach to the design of individual space-time codes is based on optimizing diversity and coding gains. This geometric approach leads to remarkable examples, such as perfect space-time block codes, for which the complexity of Maximum ...

An Efficient Differential MIMO-OFDM Scheme with Coordinate Interleaving

open access: yesEURASIP Journal on Wireless Communications and Networking, 2007
We propose a concatenated trellis code (TC) and coordinate interleaved differential space-time block code (STBC) for OFDM. The coordinate interleaver, provides signal space diversity and improves the codeword error rate (CER) performance of the system in
