| Abstract | In this study, 2-parameter cosh window is modified to improve its spectral characteristic in terms of the ripple ratio by proposing a new additional parameter. It is observed that an increase in the new parameter results in wider mainlobe width and smaller ripple ratio. By choosing the suitable combinations of the two adjustable parameters for the proposed modified window, the optimum windows that yield the minimum ripple ratio for N=51 and N=101 are found. The simulation results with the comparisons to Kaiser and cosh windows for a wide range of the normalized width demonstrate that with the proposed additional parameter an efficient improvement in the spectral characteristic of cosh window in terms of the ripple ratio is obtained. Also, two specific comparison examples are given to show the performance of the proposed modified window. In the first example, it is concluded that the proposed window performs the same ripple ratio and mainlobe width by using less window coefficients compared to Kaiser and cosh windows. The second example demonstrates that using the suitable adjustable parameters, the proposed modified cosh window can perform good results in terms of the ripple ratio and contrast ratio compared to the windows in the literature. |

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.
