Research ArticleOpen accessEvery word in the titleA New Robust Hybrid Approach to Enhance Speech in Mobile Communication SystemsManimegalai Govindan Sumithra, Keppana Gounder Thanuskodi, Bharathi DeepaProblem statement: The received voice signal in mobile communication is often disturbed by background noise and hence there is a need for good noise reduction methods for enhancing Speech. It is well known that denoising is a compromise between the removal of the largest possible amount of noise and the preservation of signal integrity. To address this issue, a new … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,299 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Efficient Causal Protocol with Forward Error Correction for Mobile Distributed SystemsEduardo Lopez Dominguez, Saul E. Pomares Hernandez, Gustavo Rodriguez Gomez et al.Problem statement: Causal ordering is used in Mobile Distributed Systems (MDS) to reduce the non-determinism induced by four main aspects: host mobility, asynchronous execution, unpredictable communication delays and unreliable communication channels. Some causal protocols have been proposed for MDS. All of these protocols in order to ensure the causal order in unreliable channels use the method of Automatic Repeat Request … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 8,239 accessesView PDFCite
