| Abstract | In this paper, we validate a green wireless communication system with the independent component analysis (ICA) based and precoding aided semi-blind equalization, on a testbed which consist of a pair of Keithley signal generator and signal analyzer connected to antennas. The implemented system requires only a small amount of side information to be transmitted to the receiver, therefore achieves energy- and spectrum-efficient green communications. The system performance is measured in different wireless channels and compared with simulation results. Compared with training data based channel equalization with overhead of 3.6%, precoding ICA equalization has a better BER performance, which gives a good tradeoff between bandwidth and energy requirement. The impact of precoding weight constant on the BER performance is showed and optimal constant value is found. The impact of frame length on the performance of ICA based equalization is also evaluated. |

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.
