| Abstract | In this paper, we focus on computing the outage probability by allocating optimal transmitting powers when the system has a large number of transmitter-receiver pairs and each mobile has an enlarged margin of SIR. By introducing a probability QoS measure scheme, we derive the moment generating function (MGF) expressions for different fading channels. Applying Chenoff bound theorem, Large Deviation theorem and MGF, we give the simple and effective expression of outage probability with the large transmitter-receiver pairs M. When M becomes larger, the upper bounds of outage probability are close to the exact outage probability curves. At the same time, for large M and lower SIR thresholds, the outage probabilities are small and very close to the exact outage probability. Numerical results have shown that each user only needs to know its own channel gain to its assigned base station and its own output at its assigned base station to update the transmitter power in order to maintain a desired signal to interference ratio (SIR) and QoS requirement at the receiver |

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.
