Space-Time Codes for Wireless Optical Communications
EURASIP Journal on Advances in Signal Processing, 2002 A space-time channel coding technique is presented for overcoming turbulence-induced fading in an atmospheric optical heterodyne communication system that uses multiple transmit and receive apertures. In particular, a design criterion for minimizing the

Unified OSTBC-based communication scheme for cooperative space vehicles
The Journal of Engineering, 2019 In many spatial cooperative vehicle networks, omni-directional communication is preferred due to its flexibility for networking. In the recent studies, space time code was shown to be an effective approach for improving the performance of the omni ...

Perfect space-time codes with minimum and non-minimum delay for any number of antennas [PDF]
2005 International Conference on Wireless Networks, Communications and Mobile Computing, 2005 We here introduce explicit constructions of minimum-delay perfect space-time codes for any number n/sub t/ of transmit antennas and any number n/sub t/ of receive antennas. We also proceed to construct non-minimal delay perfect space-time codes for any n/

MMSE Optimal Algebraic Space-Time Codes
, 2007 Design of Space-Time Block Codes (STBCs) for Maximum Likelihood (ML) reception has been predominantly the main focus of researchers. However, the ML decoding complexity of STBCs becomes prohibitive large as the number of transmit and receive antennas ...

Three-transmit-antenna space-time codes based on SU(3) [PDF]
, 2005 Fully diverse constellations, i.e., a set of unitary matrices whose pairwise differences are nonsingular, are useful in multiantenna communications especially in multiantenna differential modulation, since they have good pairwise error properties ...

Pragmatic Space-Time Codes for Cooperative Relaying in Block Fading Channels
EURASIP Journal on Advances in Signal Processing, 2008 We address the problem of construction of space-time codes for cooperative communications in block fading channels. More precisely, we consider a pragmatic approach based on the concatenation of convolutional codes and BPSK/QPSK modulation to obtain ...

Perfect Space–Time Block Codes [PDF]
, 2006 In this paper, we introduce the notion of perfect space–time block codes (STBCs). These codes have full-rate, full-diversity, nonvanishing constant minimum determinant for increasing spectral efficiency, uniform average transmitted energy per antenna and

Constructions of Fast-Decodable Distributed Space-Time Codes
, 2015 Fast-decodable distributed space-time codes are constructed by adapting the iterative code construction introduced in [1] to the N -relay multiple-input multiple-output channel, leading to the first fast-decodable distributed space-time codes for more ...
