A novel amplifier‐based transmissive space‐time‐coding metasurface is presented to realize strongly nonlinear controls of electromagnetic (EM) waves in both space and frequency domains, which can manipulate the propagation directions and adjust ...

On the existence of perfect space-time codes [PDF]
Perfect space-time codes are codes for the coherent multiple-input multiple-output (MIMO) channel. They have been called so since they satisfy a large number of design criteria that makes their performances outmatch many other codes.

Full-Diversity Space-Time Error Correcting Codes with Low-Complexity Receivers
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 ...

New space-time block codes from spectral norm.
Current research proposes a natural environment for space-time codes and a new design criterion is obtained for space-time block codes in multi-antenna communication channels.

Successive interference cancellation schemes for time-reversal space-time block codes [PDF]
In this paper, we propose two simple signal detectors that are based on successive interference cancellation (SIC) for time-reversal space-time block codes to combat intersymbol interference in frequency-selective fading environments. The main idea is to

L2 Orthogonal Space Time Code for Continuous Phase Modulation [PDF]
To combine the high power efficiency of Continuous Phase Modulation (CPM) with either high spectral efficiency or enhanced performance in low Signal to Noise conditions, some authors have proposed to introduce CPM in a MIMO frame, by using Space Time ...

Cooperative differential space-time spreading for the asynchronous relay aided CDMA uplink using interference rejection spreading code [PDF]
—This letter proposes a differential Space–Time Coding (STC) scheme designed for asynchronous cooperative networks, where neither channel estimation nor symbol-level synchroniza-tion is required at the cooperating nodes.

Space-Time Multilevel Codes [PDF]
To date there has been little work done on multilevel codes for the space-time environment. In this paper we develop multi-dimensional space-time multilevel codes (ST-MLCs), which partition the 2N/sub t/-dimensional signalling space that spans all N/sub t/ transmit antennas.

Systematic Design of Space-Time Trellis Codes for Diversity and Coding Advantages
The emerging need for high data rate wireless services has raised considerable interest in space-time coding. In this work, we propose a systematic code construction method that jointly considers diversity advantage and coding advantage for an arbitrary ...

High-rate codes that are linear in space and time [PDF]
Multiple-antenna systems that operate at high rates require simple yet effective space-time transmission schemes to handle the large traffic volume in real time.
