| Abstract | A self-calibration algorithm for Y-shaped array (SAY) is presented in the presence of mutual coupling. It utilizes special mutual coupling characteristics of Y-shaped array to decouple the azimuth (AZ)/elevation (EL) and mutual coupling coefficients of antenna array so that two kinds of parameter estimations can be realized without any calibration sources. Different from conventional self-calibration algorithm based on iterative alternating minimization technique, the proposed algorithm firstly estimates DOA by searching spectrum peak, and then estimates mutual coupling coefficients so as to avoid huge computation and global convergence problem. This literature puts emphasis on the performance analysis of new proposed algorithm. Simulation results illustrate that the proposed self-calibration algorithm has the advantages of better numerical stability and less computation load. Besides, it possesses a better performance when SNR is larger than 20dB and the number of snapshots is larger than 150. |

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.
