Prabha G and Sundaram, G. A. S., “Estimation of DOA using a Cumulant Based Quadricovariance Matrix”, 2016 10th European Conference on Antennas and Propagation (EuCAP). pp. 1-5, 2016.[Abstract]


This paper discusses the estimation of direction of arrival of narrowband signals received by a linear array. The algorithm uses fourth order cumulants of the array input data to construct a matrix whose dimension is increased by a power of two compared to the classical Multiple Signal Classification (MUSIC) and Estimation of Signal parameters using Rotational Invariance Technique (ESPRIT) algorithm. This extended matrix along with extended array steering vectors uses the steps followed by MUSIC algorithm for the calculation of direction of arrival. The proposed method is able to detect more number of sources than the elements of the array and hence helps in increasing the effective aperture size. Preprocessing using forward backward averaging is used to improve the accuracy of estimation.

V. Ranganathan, Prabha G, and Narayanankutty Karuppath, “Constant modulus hybrid recursive and least mean squared algorithm performance comparable to unscented Kalman filter for blind beamforming”, in 2016 IEEE Annual India Conference, INDICON 2016, 2016.[Abstract]


In this paper, we propose an adaptive filtering algorithm, Hybrid Recursive and Least Mean Square-based Constant Modulus Algorithm (RLS-LMS-CMA) for optimized blind beamforming for a Uniform Linear Array (ULA). We consider that Recursive Least Square-based Constant Modulus Algorithm (RLS-CMA) and Least Mean Square-based Constant Modulus Algorithm (LMS-CMA) algorithms are time tested. Therefore, we investigated a combination of RLS-LMS-CMA algorithm. We achieve similar tracking performance when compared to Unscented Kalman Filter-based Constant Modulus Algorithm (UKF-CMA) with minimal computational complexity. Simulations are carried out to compare the performance of RLS-LMS-CMA with other state-of-the-art algorithms. Results obtained indicate that proposed algorithm leads to an equivalent tracking ability and convergence rate of UKF-CMA algorithm. © 2016 IEEE. More »»
