Research ArticleOpen accessIn the keywordsMulti-Pulse Based Code Excited Linear Predictive Speech Coder with Fine Granularity Scalability for Tonal LanguageSuphattharachai ChomphanProblem statement: The flexible bit-rate speech coder plays an important role in the modern speech communication. The MP-CELP speech coder which is a candidate of the MPEG4 natural speech coder supports a flexible and wide bit-rate range. However, a fine scalability had not been included. To support finer scalability of the coding rate, it had been studied in this study. … …Journal of Computer Science, Vol. 6, Issue 11 · 24 Nov 2010 · 7,191 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEVALUATION OF HIDDEN MARKOV MODEL BASED ADAPTIVE PROVISIONING OF OPTICAL BURST SWITCHING NETWORKS AMENABLE FOR UPGRADATION TO GREEN FLEXIGRID NETWORKSP. G.V. Ramesh, Prita NairCatering to the evolving bandwidth-on-demand applications requires flexible provisioning architectures that ensure fairness to both high end and low end users of internet. Dynamic classification of network paths into long and short, based on traffic dependent connection holding times and a wavelength allocation from different subsets for these categories is a necessity for implementing energy saving hybrid switching, loss recovery … …Journal of Computer Science, Vol. 10, Issue 5 · 16 Jan 2014 · 6,517 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPattern Based Communication System and Its Performance Characteristics Compared to the Matched FilteringOzgur Orcay, Berk UstundagProblem Statement: Pattern Based Communication System (PBCS) aims to handle two prominent restrictions in communication lines. These are the inefficient utilization of the bandwidth under the spectrum limitations and sensitivity of the data transmission rate to the variation of Signal to Noise Ratio (SNR). Approach: The key point of PBCS is to construct the optimal communication signals, which consist of … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 7,288 accessesView PDF Cite
