| Abstract | We study the state-dependent multiple access channel (MAC) with causal side information at the encoders. The channel state consists of two independent components, S1 and S2, available at Encoder 1 and Encoder 2, respectively. The problem where the state is available at only one of the encoders is a special case . We consider two scenarios. In the first, the states are available at the encoders in a strictly causal manner. We derive an achievable region, which is tight for a Gaussian MAC where the state sequence comprises the channel noise and is available at one of the encoders only. In the second scenario the state sequence is available to the encoders in a causal manner, as in Shannon's model. A simple extension of the previous result to Shannon strategies yields an achievability result. Our region contains as a special case the naïve rate region obtained when each of the users applies Shannon strategies. In some cases the inclusion is strict. |

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.
