Algorithmic Design of Compression Schemes and Correction Techniques

The book explained the concepts of compression and correction techniques through easy- to-follow examples and schematic diagrams to achieve cost and time effectiveness of communication. Pivotal Difference Method(PDM) and Running Difference Method(RDM) along with repeated use(cascading) on the same input/intermediate stream has been considered to achieve better compressions. Nibble Huffman(NH),LZ and cascading of PDM and RDM are described along with comparison of results on cascading among PDM-NH,RDM-NH, PDM-LZ and RDM-LZ.Implementation of PDM,RDM and arithmetic coding on lossless/lossy image file,cascading with LZ and comparison with JPEG Lossy compression are also described. Error correction using Paired Parity Method(PPM) and its advantage in comparison with Parity Error Correction is discussed. A multilevel cascaded model for cost-effective and reliable transmission using PDM or RDM cascaded with LZ and PPO has also been discussed. All of these features make this book an ideal text for computer science, computer applications, electronics and instrumentation students. Practising engineers would also find this book to be a valuable reference source
