| Abstract | Multi-Symbol Encapsulated Orthogonal Frequency Division Multiplexing (MSE-OFDM) system, in which one cyclic prefix (CP) is used for a frame of multiple OFDM symbols in the time domain, will be widely applied in future communication systems. The main purpose of the MSE-OFDM system is to enhance the bandwidth efficiency deteriorated by the CP of each OFDM symbol in relative static wireless channel environment. In this paper, a detailed orthogonality analysis of the MSE-OFDM system is demonstrated, based on which an improvement that the OFDM symbols are encapsulated in the frequency domain is proposed. The modified system can reduce the time delay of processing in the receiver end. In the mean time it provides great flexibility for pilot insertion as traditional OFDM system. For static wireless channel, more redundancy is eliminated with nearly the same bit error rate (BER) compared to the MSE-OFDM system. While for slowly mobile channel, such as the user end is at the speed of walking, lower BER is performed. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
