Representation using the Weyl transform [PDF]

The Weyl transform is introduced as a powerful framework for representing measurement data. Transform coefficients are connected to the Walsh-Hadamard transform of multiscale autocorrelations, and different forms of dyadic periodicity in a signal are ...

Improved Quantum Linear Attacks and Application to CAST

IACR Transactions on Symmetric Cryptology
This paper studies quantum linear key-recovery attacks on block ciphers. The first such attacks were last-rounds attacks proposed by Kaplan et al. (ToSC 2016), which combine a linear distinguisher with a guess of a partial key.

Lower-Complexity Multi-Layered Security Partitioning Algorithm Based on Chaos Mapping-DWT Transform for WA/SNs

Journal of Sensor and Actuator Networks
The resource limitations of Low-Power Wireless Networks (LP-WNs), such as Wireless Sensor Networks (WSNs), Wireless Actuator/Sensor Networks (WA/SNs), and Internet of Things (IoT) outdoor applications, restrict the utilization of the error-performance ...

Use of fast Walsh-Hadamard transformation for optimalsymbol-by-symbol binary block-code decoding

Electronics Letters, 1998
A procedure for optimal symbol-by-symbol binary block-code decoding is presented: it uses the spectral Walsh-Hadamard transformation. The dimension of the Walsh-Hadamard basis is equal to that of dual codes. The realisation of the described procedure, using the fast Walsh-Hadamard transformation application, is seen to be the most efficient in terms of

PAPR Reduction of OTSM with Random and Orthogonal SLM Phase Sequences and its Recovery in the Presence of EPA, EVA and ETU Channel Models [PDF]

Radioengineering
To overcome the high peak-to-average-power ratio (PAPR) in orthogonal time sequency multiplexing (OTSM), this document proposes orthogonal and random selective mapping phase vectors (OSLM and RSLM) after some modifications to be applicable with OTSM ...
