| Abstract | Reduction of peak-to-average power ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) system using the partial transmit sequence (PTS) approach. In PTS, the total search for the number of subblocks and the rotation factors must be accomplished. As the number of subblocks and rotation factors increases, PAPR reduction improves. The number of calculation increases as the number of subcarriers increases, such that complexity increases exponentially and the process delay occur simultaneously. In this paper, a modified PTS scheme combined with interleaving technique for PAPR reduction has been presented. The scheme is very effective and avoids the use of any extra Inverse Fast Fourier Transformations (IFFTs) as was done in PAPR reduction by ordinary PTS technique when dividing the various subcarriers into different subblocks. The simulation result shows that PAPR performance is improved in comparison with the modified PTS and computational complexity is reduced. |

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.
