Code diversity in multiple antenna wireless communication
, 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 ...

Cyclic division algebras: a tool for space-time coding [PDF]
, 2007 Multiple antennas at both the transmitter and receiver ends of a wireless digital transmission channel may increase both data rate and reliability. Reliable high rate transmission over such channels can only be achieved through Space–Time coding.

Full-diversity design criterion for multi-user STBC based on integer-forcing detection
Tongxin xuebao, 2019 Multi-user space time block code systems have the problem of high decoding complexity.To ensure good system performance with low decoding complexity at the same time,low complexity integer-forcing (IF) detection algorithm was applied to multi-user space ...

An Efficient Differential MIMO-OFDM Scheme with Coordinate Interleaving
EURASIP 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

Differential Space-Time Block Code Modulation for DS-CDMA Systems
EURASIP Journal on Advances in Signal Processing, 2002 A differential space-time block code (DSTBC) modulation scheme is used to improve the performance of DS-CDMA systems in fast time-dispersive fading channels. The resulting scheme is referred to as the differential space-time block code modulation for DS-

A Phase Feedback Based Extended Space-Time Block Code for Enhancement of Diversity
IEEE Vehicular Technology Conference, 2007 In this paper we propose a generalization of extended orthogonal space-time block codes (EO-STBCs) for MIMO (multi-input/multi-output) channels using four transmit antennas for quasi-static flat fading channels.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
