| Abstract | In this paper, a low complexity peak-to-average power ratio (PAPR) reduction scheme is proposed for OFDM systems. By utilizing the properties of Discrete Fourier Transform (DFT), the proposed scheme divides the OFDM symbol into two disjoint subblocks in time domain, and generates a set of candidate signals by cyclically shifting one of the subblocks and sums them up. From the candidate signals, the one with the minimum PAPR is selected to be transmitted. Compared with selected mapping (SLM) and partial transmitted sequences (PTS), the proposed method needs only one IFFT and no additional complex multiplication operation, which means that the computational complexity of this method is significantly lower than SLM and PTS. When the number of candidate signals is limited, simulation results show that the PAPR performance of the proposed method is slightly worse than that of SLM, but outperforms PTS. |

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.
