Abstract | This paper analyzes the problem of decoding order and rate allocation in DS-CDMA cellular systems using successive interference cancellation (SIC) technology. Two different constraints, i.e. the maximum transmission power of users and the system throughput, are considered respectively. When the maximum transmission power of users is limited, this paper first proposes a theorem to assert whether or not the system is feasible, and then the optimal decoding order algorithm based on the feasible solution is given for some special cases. When the system throughput is an issue, the rate allocation should also be considered besides the decoding order. In this case, an algorithm to find the optimal solution is given first, and then a suboptimal solution is given to reduce the computation complexity. Different user cost factors are considered in both cases, and the methodologies and corresponding results of the analyses can be used as a reference to real system operating, access control and scheduling, etc |

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.
