Nowadays, the attacks on the Internet are becoming more complex, advanced and concealed. A large number of security threats arise. The signature-based detection technology is efficient and simple which is widely used for malicious codes detection system. In this paper, we firstly focus on the principle of the method, and summarize the specific steps to implement it, especially feature extraction,...
We consider relay selection in a multiple source-destination cooperative network with multiple potential relays. Interference induced by simultaneous transmissions makes relay selection different from interference-free scenarios which has not been well addressed in literature. In this paper, we propose a new relay selection metric in interference-limited networks in order to improve network throughput...
Precision analysis and optimization is very important when transforming a floating-point algorithm into fixed-point hardware implementations. The core analysis techniques are either based on dynamic analysis or static analysis. We believe in static error analysis, as it is the only technique that can guarantee the desired worst-case accuracy. In this paper we study various underlying arithmetic candidates...
Vegetation parameters can be estimated using the single-baseline polarimetric synthetic aperture radar interferometry (POLinSAR) data based on the random volume over ground (RVoG) model. Temporal decorrelation, which is the coherence loss due to scene changes within the time between radar data acquisitions, will decrease the estimation accuracy and needs to be compensated. The RVoG+VTD model is a...
