Performance analysis of TLS-Esprit and QR TLS- Esprit algorithm for Direction of Arrival estimation

In this paper the performance analysis of TLS-Esprit, QR TLS-Esprit for Direction of Arrival(DOA) estimation is evaluated in terms of the root mean square DOA error. In these paper, exploring the Eigen analysis category of high resolution and super resolution algorithms, presentation and description, comparison and the performance and resolution analyses of these algorithm are made. These high resolution parameter estimation algorithms were designed to provide a reduced estimation error that is explicit in the noise realizations and asymptotic in the effective signal to noise ratio (SNR), i.e. the approximation becomes exact for high SNRs or a large sample size.
