| Abstract | In this paper, an Interference Cancellation Algorithm using superdirective beamforming and adaptive noise cancelling (ANC) is proposed. The only assumption is that the source and the interference directions are coarsely known in advance. The noisy source signal of which the interference is reduced to some degree after beamforming, is processed by ANC in order to cancel out the residual interference left on the desired signal. In the proposed algorithm, the required noise-only reference signal for ANC is acquired by beamforming in the direction of the noise source. In this sense, proposed scheme is similar to well-known Generalized Sidelobe Canceller (GSC) algorithm. However, the directions of source and interference not need to be known exactly and it has much less implementation complexity compared to GSC. Thus, the proposed scheme is possible to be employed in microphone array systems with high number of microphones in real-time and without any need to know the directions, it can work in real life scenarios where knowing the exact positions are not realistic. The proposed scheme is verified by computer simutaions and real-life experiements. |

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.
