| Abstract | Efficiency of telecommunication system is affected by the amplifier used in it. In this study, it is investigated the deterioration effect of resampling on modeling performance of that system. Digital predistortion system is used to linearize Amplifier and Unit Delay memory modeling technique is used to model amplifier behavior. Two different amplifier responses is stored in order to determine the resampling effect on DPD performance, while the first measurement result has not been resampled the other one is resampled. While there is very good improvement in the spectral regrowth for the former measurement, the later has lower improvement on DPD performance due to resampling deterioration effect. In order to diminish distortion effect of resampling when it is necessary, a new way for measurement and resampling is developed. Measurement time is increased a bit and fft filter is applied while resampling the signal. Comparable result have been reached with this new technique with respect to the technique doesn't needn't resampling. |

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.
