Data <span>transmission in orthogonal frequency division multiplexing (OFDM) system needs source and channel coding, the transmitted data suffers from bad effect of large peak to average power ratio (PAPR). Source code codes can be joined using different codes. Variable length error correcting (VLEC) is one these VLEC used mat lab simulation for image transmission OFDM system, compared fi...

Efficient optimal prefix coding has long been accomplished via the Huffman algorithm. However, there is still room for improvement and exploration regarding variants of the Huffman problem. Length-limited Huffman coding, useful for many practical applications, is one such variant, for which codes are restricted to the set of codes in which none of the n codewords is longer than a given length, ...

Modern daily life activities produced lots of information for the advancement telecommunication. It is a challenging issue to store them on digital device or transmit it over Internet, leading necessity data compression. Thus, research compression solve has become topic great interest researchers. Moreover, size compressed generally smaller than its original. As result, saves storage and increa...

<span>In wireless sensor network (WSN), the high volume of observe and transmitted data among nodes make it requires to maintain security. Even though numerous secure transmission approaches designed over a network, an inadequate resource complex environment cause not able used in WSNs. Moreover, communication is big challenging problem WSNs especially for military application. This paper...

Generally, data mining is the process of analyzing data from different perspectives and summarizing it into useful information information that can be used to increase revenue, cuts costs, or both. Data mining software is one of a number of analytical tools for analyzing data. It allows users to analyze data from many different dimensions or angles, categorize it, and summarize the relationship...

LOCO-I (LOw COmplexity LOssless COmpression for Images) is a novel lossless compression algorithm for continuous-tone images which combines the simplicity of Huffman coding with the compression potential of context models, thus “enjoying the best of both worlds.” The algorithm is based on a simple fixed context model, which approaches the capability of the more complex universal context modelin...
