| Abstract | A novel coding scheme for ECG data compression is proposed in this paper. Following beat delineation, the periods of the beats are normalized by multi-rate processing. Amplitude normalization is performed afterwards, and discrete wavelet transform is applied to each normalized beat. Due to the period and amplitude normalization, the wavelet transform coefficients bear a high correlation across beats. To increase the compression ratio, a pattern matching unit is utilized. The difference between the actual period and the standard period, and amplitude scale factor are also retained for each beat. At the decoder, the inverse wavelet transform is computed from the reconstructed wavelet transform coefficients. The original amplitude and period of each beat are then recovered. The simulation results show that the performance of the proposed compression algorithm is quite satisfactory and achieves significant improvement in comparison with some recent techniques. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
