| Abstract | High throughput satellite systems are expected to rely in the user link on multi-beam architectures with small beam footprints and strong frequency reuse among beams, and will therefore operate in an interference limited regime. In this paper, the focus is set on the forward link of a multi-beam broadband satellite system, and linear precoding is considered to mitigate this increased level of interference among users. The contribution of the present work is twofold. First, assuming a single gateway scenario, we analytically prove the benefit of considering the precoding in the feed space, that is, not considering the presence of on-board beamforming. Second, for taking into account realistic feeder link bandwidth restrictions, we consider a multiple gateways scenario where each gateway is serving a cluster of adjacent cells. We propose an architecture which includes precoding in the feed space at each gateway, and derive a zero-forcing precoder design which mitigates both the inter and intra-cluster interference. |

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.
