| Abstract | This paper proposes a model for further effective use of frequency and power of the future generation wireless communications by superconducting filter. The transmit amplifier SSPA (solid state power amplifier) has conventionally been used at its linear region by taking enough back-off in order to compress the out-band spectrum spreading. We constituted a computer simulation for the evaluation of the transmission performance of OFDM (orthogonal frequency division multiplexing) modulation in the nonlinear channel of SSPA with the sharp transmit filter of superconducting filter for 5 GHz band base station including fading. As the result of the simulation, we can save 3-5 dB of the SSPA power in the model. Moreover, the channel interval can be reduced by about 30% in frequency by the steep attenuation outside band characteristics. It is expected that the SSPA can be with small back-off and also advantageous in power consumption by using the superconducting filter. |

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.
