| Abstract | The error probability is one of the important metrics used to measure the performance of cooperative relay-based systems. Conventionally, the error probability analysis assumes no information about the condition of the Source-Relay link. In this paper, we show that this assumption could result in over or under estimation of the error probability and therefore affects the accuracy of the analysis which is essential to design optimum relay-based system. Therefore, we propose the mathematical model of conditional error probability, in which relay decision information is considered in the performance analysis of cooperative relay-based systems. The mathematical model for Hybrid Decode-Amplify-Forward cooperative system is utilized in order to validate the necessity of modeling conditional error probability and evaluate the overall system performance. The accuracy of the derived analytical expressions are validated via Monte Carlo simulations. Results show that, there is substantial difference between the conventional and the conditional error probability, which depends on relay decision information. Finally, the derived expressions provide accurate analytical tool to analyze and design relay-based cooperative systems for various Source-Relay channel conditions. |

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.
