Dr. Kaluri V. Ranga Rao of JNTU at Hyderabad India

The current talk is based on authors past few years and a accepted paper at ICSP 2018 at Beijing China,IEEEProceedings of ICSP18 pp 903-908). There are many methods in DOA estimation[1][2][3], each catering to a domain specific requirement. The current method is aimed at lean computing and leaves the computing band-width to other applications. The speaker will be presenting gold-Fourier-Kaluri(gFK) method and kMUSIC, a novel method for estimating Direction of Arrival (DOA) for Classifying Multiple SIgnals (κMUSIC) by reducing the spectrum to sum of monochromatic signals or pure tones. This is achieved by exploiting gFK method for providing these phasors at each spectral peak. A complex beam steering vector is generated for obtaining the DOA. Results are presented and compared with standard MUSIC for reference and tested with field data for performance.
