Space-time block codes with rate >= 1 for power line channels [PDF]
, 2002 In this paper, the utilisation of space-time block codes (STBC) for high-speed communications over power line channels (PLC) affected by quasi-static flat Rayleigh fading and additive man-made asynchronous impulsive noise is presented.

Layered Steered Space-Time Codes Using Iterative Detection
, 2007 This paper presents a novel multifunctional multiple-input multiple-output (MIMO) scheme that combines the benefits of the Vertical Bell Labs Layered Space-Time (VBLAST) scheme, of Space-Time Codes (STC) as well as of beamforming.

Full-Diversity Space-Time Error Correcting Codes with Low-Complexity Receivers
EURASIP Journal on Wireless Communications and Networking, 2011 We propose an explicit construction of full-diversity space-time block codes, under the constraint of an error correction capability. Furthermore, these codes are constructed in order to be suitable for a serial concatenation with an outer linear ...

Space-time-coding digital metasurfaces [PDF]
Nature Communications, 2018 AbstractThe recently proposed digital coding metasurfaces make it possible to control electromagnetic (EM) waves in real time, and allow the implementation of many different functionalities in a programmable way. However, current configurations are only space-encoded, and do not exploit the temporal dimension. Here, we propose a general theory of space-

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

Generalized PSK in Space–Time Coding [PDF]
IEEE Transactions on Communications, 2005 A wireless communication system using multiple antennas promises reliable transmission under Rayleigh flat fading assumptions. Design criteria and practical schemes have been presented for both coherent and non-coherent communication channels. In this paper we generalize one dimensional phase shift keying (PSK) signals and introduce space time ...

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 ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Joint Estimation and Decoding of Space-Time Trellis Codes
EURASIP Journal on Advances in Signal Processing, 2002 We explore the possibility of using an emerging tool in statistical signal processing, sequential importance sampling (SIS), for joint estimation and decoding of space-time trellis codes (STTC).
