High-Rate Spatial Modulation Transmission Scheme With Block-Orthogonal Structure and Block-by-Block Sphere Decoding

open access: yesIEEE Access, 2020
The work in this paper is an extension of the recently proposed stacked Alamouti based spatial modulation (SA-SM) scheme. The motivation is that by taking advantage of the existing full-diversity full-rate (FDFR) space-time code, to construct SM ...

Variable-rate source coding theorems for stationary nonergodic sources [PDF]

open access: yes, 1994
For a stationary ergodic source, the source coding theorem and its converse imply that the optimal performance theoretically achievable by a fixed-rate or variable-rate block quantizer is equal to the distortion-rate function, which is defined as the ...

Case Study: Design Strategies for Enabling Visual Application Blocks of Bluetooth Library

open access: yesIEEE Access, 2022
Block-based tools can make it easier for beginners to learn programming by arranging blocks. Their block concept and extensible characteristics make block-based designs suitable for introductory programming. However, block-based tools are easy to use but

CAMFuzz: Explainable Fuzzing with Local Interpretation

open access: yesCybersecurity, 2022
Grey-box fuzzing techniques have been widely used in software bug finding. In general, there are many decisions to make in the fuzzing process, including which code block in the target program should be explored first, which bytes of an input seed should

BlockMatch: A Fine-Grained Binary Code Similarity Detection Approach Using Contrastive Learning for Basic Block Matching

open access: yesApplied Sciences, 2023
Binary code similarity detection (BCSD) plays a vital role in computer security and software engineering. Traditional BCSD methods heavily rely on specific features and necessitate rich expert knowledge, which are sensitive to code alterations.
