Giridhar, P.V.S.Narasimhan, S.V.2020-03-312020-03-312000Sadhana - Academy Proceedings in Engineering Sciences, 2000, Vol.25, 2, pp.85-96https://idr.nitk.ac.in/handle/123456789/11571An improved system blind identification method based on second-order cyclostationary statistics and the properties of group delay, has been proposed. This is achieved by applying a correction to the estimated phase (by the spectral correlation density of the system output) for the poles, in the group delay domain. The results indicate a significant improvement in system blind identification, in terms of root mean square error. Depending upon the signal-to-noise ratio, the improvement in percentage normalized mean square error ranges between 20 and 50%.Article
