Super-Orthogonal Space-Time Turbo Transmit Diversity for CDMA
EURASIP Journal on Advances in Signal Processing, 2005 Studies have shown that transmit and receive diversity employing a combination of multiple transmit-receive antennas (given ideal channel state information (CSI) and independent fading between antenna pairs) will potentially yield maximum achievable ...

Reduced-complexity transmit/receive-diversity systems [PDF]
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002 We consider wireless systems with transmit and receive diversity. For reduction of complexity, we propose to use hybrid selection/maximal-ratio transmission at one link end, choosing L out of N antennas. We analyze the performance of such systems, giving analytical bounds and comparing them with computer simulations.

Coherent Code Tracking for Spatial Transmit Diversity DS-CDMA Systems
EURASIP Journal on Advances in Signal Processing, 2005 Spatial transmit diversity schemes are now well integrated into third-generation cellular mobile communication system specifications. When DS-CDMA-based technology is deployed in typical macro- and microcell environments, multipath diversity and spatial ...

Compressed Sensing Improves the Performance of Subcarrier Index-Modulation-Assisted OFDM
IEEE Access, 2016 In orthogonal frequency division multiplexing relying on subcarrier index modulation (OFDM-SIM), the information is conveyed by both the indices of the activated subcarriers and the conventional amplitude-phase modulated (APM) symbols.

Achieving Transmit Diversity in OFDM-IM by Utilizing Multiple Signal Constellations
IEEE Access, 2017 Orthogonal frequency division multiplexing (OFDM) index modulation (IM) is a novel multicarrier modulation, which employs both the indices of the active subcarriers and conventional constellation symbols to convey information.

On the Capacity of Certain Space-Time Coding Schemes
EURASIP Journal on Advances in Signal Processing, 2002 We take a capacity view of a number of different space-time coding (STC) schemes. While the Shannon capacity of multiple-input multiple-output (MIMO) channels has been known for a number of years now, the attainment of these capacities remains a ...

BER Analysis of STBC Codes for MIMO Rayleigh Flat Fading Channels [PDF]
Telfor Journal, 2012 The paper presents the analysis of Space-Time Block Codes (STBC) used in Multiple-Input Multiple-Output (MIMO) systems to assure transmit diversity. The receive diversity is resolved with a Maximum Ratio Combining technique.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
