LL‐FMC: Low‐latency frame memory compression scheme with high reconstructed quality
Electronics Letters, Volume 59, Issue 14, July 2023., 2023 This study proposes a Huffman coding with a fixed codebook designed to considerably reduce the latency caused by arithmetic coding in lossless compression schemes. This study also proposes a novel lossy frame memory compression technique based on the Hadamard transform that does not require additional memory access using a lookup table.

Sparse representation based intraframe and semi‐intraframe video coding schemes for low bitrates
IET Image Processing, Volume 15, Issue 5, Page 1128-1143, April 2021., 2021 Abstract This paper proposes some extensions of the successful sparse coding of still images to intraframe and semi‐intraframe video coding. The presented frameworks apply the efficient K‐singular value decomposition and recursive least squares dictionary learning methods for sparse representation of videos to study their coding performances.

The Methods toward Improving Communication Performance in Transparent Radio Frequency Signals
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 In wireless digital communications, amplitude‐shift keying (ASK) and frequency‐shift keying (FSK) modules are often used and radio frequency (RF), communication synchronization, and noise problems affect the performance very much. In particular, the sending of byte‐type data called synchronous and preamble before sending data in intermodule ...
