| Abstract | This work reports for the first time the characterization and the bi-dimensional shaping function for a dual-band 10W ET-PA operating in concurrent mode at 870 and 1950 MHz. The characterization involved WCDMA 6.5 PAR excitation, and a detailed analysis of the signals statistic resulting from the ET mode is reported as well. The measured data reported an average DE for the concurrent modes of 49.2 %, while we observed a significant variation of the PAR, with respect to single band operation. We demonstrate that this PAR variation is due to the specific gain versus power level shape, which is established during the concurrent ET-PA operation. |

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.
