| Abstract | Cooperative relaying is a promising alternative for conventional mobile communications systems as it is able to increase coverage and throughput of these systems. Due to practical constraints most cooperative relaying protocols employ half-duplex relays which implies the need for an increased data rate on the individual links and causes a significant performance loss at higher rates. This paper presents a novel cooperative relaying approach exploiting existing large scale space diversity as well as an additional coding gain by employing a spatial duplex approach. The scheme utilizes a network of alternatingly sending and receiving relay terminals where only one relay node is transmitting at a particular time. This spatial duplexing approach is used to implement a distributed Space-Time Trellis Code (STTC) for virtual antenna arrays. In this work, the protocol is applied to a convolutionally coded system. Due to the serial concatenation of an inner STTC and an outer convolutional code, the destination is able to use well-known turbo-decoding algorithms to reduce the frame error rate of the system. The assessment of the approach is done by comparing it with conventional relaying, a time/frequency duplex cooperative relaying protocol and direct transmission. |

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.
