Research ArticleOpen accessIn the abstractImplementation of a Novel Concatenated FEC by RS and Irregular Turbo Codes on OFDM SystemsA. Shanmugam, A. R. Abdul Rajak, S. Vishwanath, R. UpendraCode Division Multiple Access (CDMA) performs well in a multi-cellular environment where a single frequency is used in all cells. Code Division Multiple Access (CDMA) has severe problems associated with multipath and Channel news. One possible problem is that the receiver may require a very large dynamic range in order to handle the large signal strength variation among users. Due … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,039 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Symbolic Threshold: A Dynamic form of the Mind as an Expression of Radiant ThinkingFelice Corona, Francesco Perrotta, Emilia Tartaglia Polcini, Carla CozzarelliProblem statement: The definition of "symbolic species" used by Terrence W. Deacon means more complete the process of monitoring the encounter between semiotics and cognitive sciences neurosemiotics better defined. Approach: The mechanism of the symbolic threshold means that it is put in place an approach to reality no longer seen as a representative of simple association, but under a restructuring … …Neuroscience International, Vol. 1, Issue 2 · 31 Dec 2010 · 16,057 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDEACT: Hardware Solution to Rowhammer AttacksTesfamichael Gebregziabher Gebrehiwot, Fitsum Assamnew Andargie, Mohammed IsmailDynamic Random Access Memory (DRAM) is a crucial component in modern computing devices. Improvements in process technology have significantly increased the speed and storage capacity of memory devices. However, as memory cells become smaller and closer to one another, annoying circuit disturbance errors such as the Row-hammer problem have become significant. Studies show that attackers can systematically exploit such errors … …Journal of Computer Science, Vol. 19, Issue 7 · 22 Jun 2023 · 6,483 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMIGITATION OF INTER CELL INTERFERENCE AND FADING IN LTE SYSTEMSNagarajan Amutha Prabha, Gorla Vidhya Sagar, Venugopal ManikandanIn this study we investigate the compensation of outage area utmost. It introduces the self optimization of the neighbors of the outage cells with antenna tilts for the generation of the most suitable configuration settings for the network with base stations/eNodeBs positional information. All the neighbors of the outage cell increase their coverage area and thus contribute to cell outage … …Journal of Computer Science, Vol. 10, Issue 3 · 28 Nov 2013 · 6,736 accessesView PDF Cite
