| Abstract | Physical-layer network coding (PNC) is a promising technique to improve the performance of wireless networks. In a traditional setting, two packets are encoded with PNC. However, encoding three or more packets with PNC may further enhance the performance. A straightforward method to achieve multiple packet encoding is to further process the superposed signal from different source node-pairs at the relay, and broadcast a jointly encoded packet to the destinations. After receiving the jointly encoded packet, each destination can decode the packet it intends to receive, based on the packet transmitted by itself and overheard packets from other node-pairs. An important issue that arises is how to determine which node-pairs should be encoded together and how to jointly encode these packets. This paper aims to solve this issue. We first propose a joint encoding method for multiple node-pairs, and then propose a method to determine the grouping of different node-pairs so that node-pairs in the same group can perform joint encoding. The proposed scheme is not restricted to a particular signal constellation, and, in principle, it can be applied to any type of signal constellations. Simulation results show that the proposed scheme can bring throughput improvement compared to schemes which only encode two packets together, the resulting throughput is also close to the optimum. |

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.
