Medical image encryption using multi chaotic maps
Over the last twenty years, chaos-based encryption has been an increasingly
popular way to encrypt and decrypt data using nonlinear dynamics and
deterministic chaos. Discrete chaotic systems based on iterative maps have
gotten a lot of interest…

Low-profile frequency-reconfigurable antenna for 5G applications
The demand for higher data rates has increased in recent years.
The reconfigurable antenna that operates in the millimeter-wave spectrum
(23.5 GHz – 29.64 GHz) was developed. This design is obtained by merging
a half-circle radius of 3.97 mm, and…

Decoding of the extended Golay code by the simplified
successive-cancellation list decoder adapted to multi-kernel polar codes
This paper describes an adaptation of a polar code decoding technique in
favor of the extended Golay code. Based on the bridge provided by a
permutation matrix between the code words of these two classes of codes,
the Golay code can be decoded by…
