Golden space-time block coded modulation [PDF]
In this paper we present a block coded modulation scheme for a 2 x 2 MIMO system over slow fading channels, where the inner code is the Golden Code. The scheme is based on a set partitioning of the Golden Code using two-sided ideals whose norm is a power of two.

Improved Perfect Space-Time Block Codes [PDF]
The perfect space-time block codes (STBCs) are based on four design criteria - full-rateness, non-vanishing determinant, cubic shaping and uniform average transmitted energy per antenna per time slot. Cubic shaping and transmission at uniform average energy per antenna per time slot are important from the perspective of energy efficiency of STBCs.

Space-time block coding for spatial modulation
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 ...

On permutation of space‐time‐frequency block codings
Multi‐input multi‐output‐orthogonal frequency‐division multiplexing is the foundation of next generation of wireless communication systems and space‐time‐frequency block coding (STFBC) is considered one of the best schemes for implementing these systems. STFBCs have very complex structures and many parameters affect their performance.

Block turbo codes for space-time systems
Advances in the field of information theory have shown that wireless systems using multiple transmitters and multiple receivers can significantly improve the spectral efficiency. Systems using transmit and receive diversity associated with coding such as space time trellis codes have since been developed.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Perfect space-time block codes and high performance decoding algorithm
Based on the structure of perfect space-time block codes(STBC),an equivalent vertical Bell Laboratories layered space-time(V-BLAST) decoding model was given.Minimum mean-square error decision feedback equalizer(MMSE-DFE) was used to preprocess this model
