Abstract | The performance of turbo TCH codes is analyzed in a (code spreading) CS-CDMA scheme, for spread spectrum applications in a multiuser and fast fading channel environment, with and without multipath. Several rates are considered, bearing in mind different types of service. In order to get an estimate of performance gains over an existing (direct sequence) DS-CDMA system, UMTS coding results are used for comparison against punctured turbo TCH codes, in order to compare equal coding rates. A simulator with the main code structure for both schemes was built, alongside the channel model and RAKE receiver, in order to correctly compare both coding schemes. Specific test conditions are defined, and the overall codes of both schemes are compared. |

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.
