| Abstract | Aiming at actual evaluation of IMT-Advanced system performance using field tests, this paper presents a developed IMT-Advanced testbed system with transmission bandwidth of 100 MHz. IMT-Advanced supports the "new capability of systems beyond IMT-2000" as indicated by the ITU-R van diagram [1] and requires a peak data rate of 1 Gbps with low mobility. In consideration of the enhanced IMT-2000 systems undergoing standardization, orthogonal frequency division multiple access (OFDMA) with multi-input multi-output (MIMO) are also promising technologies in the IMT-Advanced system. In addition, in order to meet the requirements for IMT-Advanced, the system seems to have about 100 MHz bandwidth with the aid of MIMO transmission. The developed system is based on the above prediction regarding the IMT-Advanced era, which is a more reliable prediction compared with previous studies, and the goals of this development are to provide a more realistic transmission performance, judgment criteria for operators introducing new air interfaces, and to explore new applications. In addition, the testbed enables us to conduct feasibility studies of rotational OFDM (R-OFDM) and the twin turbo decoder, which is our previous work [2] [3]. This paper performs pre-experiments before field tests, and verifies that the testbed transmits signals with 100 MHz bandwidth and the coverage providing a throughput of more than 100 Mbps without MIMO will reaches about 650 m. |

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.
