| Abstract | Cylindrical cells represent actual service volumes used in terminal areas (airports) for air traffic control (ATC) communications between pilots and ground controllers. The channel capacities of simplex and duplex frequency division multiplexing (FDM) mobile air/ground (A/G) radio communication systems employing cylindrical cells are compared assuming a network of identical cylindrical cells and a dedicated radio channel per group of aircraft and its ground controller. The two systems are compared considering both cochannel and adjacent channel interferences for analog and digital modulation. Then, capacities of duplex FDM and code division multiplexing (CDM) are compared under the same assumptions for digital modulation. The capacity of FDM depends mainly on the frequency reuse distance while the capacity of CDM is limited by the self users interference. This work shows that the capacity ratio of duplex and simplex FDM systems depends on the cell dimensions. It also shows that considering ATC requirements, FDM provides a higher capacity than CDM for all the cell dimension ranges considered. |

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.
