Space-Time block codes from orthogonal designs
TLDR
A generalization of orthogonal designs is shown to provide space-time block codes for both real and complex constellations for any number of transmit antennas and it is shown that many of the codes presented here are optimal in this sense.

Space-Time Codes for High Data Rate Wireless Communications : Performance criterion and Code Construction
TLDR
Winding sections are assembled coaxially with one of the winding sections being of the encapsulated type and the other of the sealed type.

Space-time block coding for wireless communications: performance results
TLDR
It is shown that using multiple transmit antennas and space-time block coding provides remarkable performance at the expense of almost no extra processing.

Quantum error correction via codes over GF(4)
TLDR
In the present paper the problem of finding quantum-error-correcting codes is transformed into one of finding additive codes over the field GF(4) which are self-orthogonal with respect to a certain trace inner product.

Wavelet Transforms That Map Integers to Integers
TLDR
Two approaches to build integer to integer wavelet transforms are presented and the precoder of Laroiaet al., used in information transmission, is adapted and combined with expansion factors for the high and low pass band in subband filtering.

Layering as Optimization Decomposition: A Mathematical Theory of Network Architectures
TLDR
A survey of the recent efforts towards a systematic understanding of layering as optimization decomposition, where the overall communication network is modeled by a generalized network utility maximization problem, each layer corresponds to a decomposed subproblem, and the interfaces among layers are quantified as functions of the optimization variables coordinating the subproblems.

Orthogonal Time Frequency Space Modulation
TLDR
Results show that even at very high Dopplers (500 km#x002F;h), OTFS approaches channel capacity through linear scaling of throughput with the MIMO order, whereas the performance of OFDM under typical design parameters breaks down completely.

The Z4-linearity of Kerdock, Preparata, Goethals, and related codes
TLDR
Certain notorious nonlinear binary codes contain more codewords than any known linear code and can be very simply constructed as binary images under the Gray map of linear codes over Z/sub 4/, the integers mod 4 (although this requires a slight modification of the Preparata and Goethals codes).

Combined Array Processing and Space-Time Coding
TLDR
This paper dramatically reduces encoding and decoding complexity by partitioning antennas at the transmitter into small groups, and using individual space-time codes, called the component codes, to transmit information from each group of antennas.

Quantum Error Correction and Orthogonal Geometry
A group theoretic framework is introduced that simplifies the description of known quantum error-correcting codes and greatly facilitates the construction of new examples. Codes are given which map 3…
