Abstract | In this work, Expectation-Maximization type receiver for uplink of an MC-CDMA system based on a time sharing hopped communication technique is proposed in order to cope with the multipath fading effect in a wireless communication system. In the proposed time-sharing hopped communication method, managing mechanism determines each user channel quality knowledge by controlling the quality of the channels between users and it. In order to present a higher quality transmission for the users with low quality channels, managing mechanism gives an opportunity to them to send their message over the users with high quality channels in time sharing mode. Thus, transmission quality for the users with low quality channel is improved. The performance of the proposed receiver, with/without hopping and with cooperative communication technique, is analysed for multipath flat fading channels by computer simulation, and results are presented. |

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.
