| Abstract | A canceller is designed to suppress undesired interference in an 802.11b WLAN radio from a Bluetooth radiator operating close to it. The design utilizes 0.18 mum CMOS IC technology. The system consists of a core that emulates the interference-coupling channel between the two radios by time domain amplitude and phase alignment, and filtration. This is controlled by an adaptive loop. Using low noise design principles, the canceller core maintains a low output noise power spectral density of -173 dBm/Hz at the center frequency of the WLAN band. The consequent degradation of WLAN receiver sensitivity is 2.7 dB while achieving at least 15 dB of interference suppression. The canceller core dissipates 20 mW of power. |

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.
