Geometrical Relations Between Space–Time Block Code Designs and Complexity Reduction [PDF]
IEEE Transactions on Information Theory, 2005 In this work, the geometric relation between space- time block code design for the coherent channel and its noncoherent counterpart is exploited to get an analog of the information-theoretic inequality I(X;S)lesI((X,H);S) in terms of diversity.

Space-frequency block code for MIMO-OFDM communication systems with reconfigurable antennas [PDF]
Global Communications Conference, 2013 We propose a space-frequency (SF) block coding scheme for a multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system using antennas with reconfigurable radiation patterns.

Generalized Cut Functions and n-Ary Block Codes on UP-Algebras
Journal of Mathematics, 2022 In this paper, the work is comprised of n-ary block codes for UP-algebras and their interrelated properties. n-ary block codes for a known UP-algebra is constructed and further it is shown that for each n-ary block code U, it is easy to associate a UP ...

Hybrid Code Lifting on Space-Hard Block Ciphers
IACR Transactions on Symmetric Cryptology, 2022 There is a high demand for whitebox cryptography from the practical use of encryption in untrusted environments. It has been actively discussed for two decades since Chow et al. presented the whitebox implementation of DES and AES. The goal is to resist

Digital Presentation and Preservation of Cultural and Scientific Heritage, 2017 3D digitization is becoming the norm in the preservation of tangible cultural properties be it movable or immovable. In the case of mobile cultural objects, 3D models are normally acquired through non-destructive methods such as photogrammetry or 3D ...

Low-Complexity Sliding Window Block Decoding Using Bit-Flipping for OVFDM Systems
IEEE Access, 2017 Overlapped frequency division multiplexing (OVFDM) systems can obtain high spectral efficiency (SE), which is proportional to the constraint length. However, high decoding complexity imposes the main challenge on OVFDM systems.
