Code Synchronization Algorithm Based on Segment Correlation in Spread Spectrum Communication

open access: yesAlgorithms, 2015
Spread Spectrum (SPSP) Communication is the theoretical basis of Direct Sequence Spread Spectrum (DSSS) transceiver technology. Spreading code, modulation, demodulation, carrier synchronization and code synchronization in SPSP communications are the core

Comparison of Frequentist and Bayesian Meta-Analysis Models for Assessing the Efficacy of Decision Support Systems in Reducing Fungal Disease Incidence

open access: yesAgronomy, 2020
Diseases of fruit and foliage caused by fungi and oomycetes are generally controlled by the application of fungicides. The use of decision support systems (DSSs) may assist to optimize fungicide programs to enhance application on the basis of risk ...

Long PN code based DSSS watermarking [PDF]

open access: yes2011 Proceedings IEEE INFOCOM, 2011
Cyber crimes often involve complicated scenes. In this paper, we investigate unidentified crimes committed through anonymous communication networks. We developed a long Pseudo-Noise (PN) code based Direct Sequence Spread Spectrum (DSSS) flow marking technique for invisibly tracing suspect anonymous flows.
