| Abstract | A novel parallel interference cancellation receiver for QAM modulated turbo coded uplink MC- CDMA systems has been proposed. In the receiver, the multi-stage partial soft parallel interference cancellation has been applied. The receiver employs the new adaptive minimum mean square combining, so that the system is able to adjust the equalization gain coefficients in every iterative stage adaptively. In addition, unlike some previous work that has drawbacks of the complexity, latency and error amplification resulting from the decoder in every iteration step, the soft in soft out (SISO) inverse bit mapper and simplified SISO bit mapper are used in the receiver. The partial cancellation is also implemented to further improve the receiver performance. The simulations are carried out in a realistic multi-user environment: modified 802.16 Stanford University Interim (SUI) channel model. Both analysis and simulations indicate that our proposed receiver can achieve a considerably good performance with a low complexity structure compared with traditional systems. |

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.
