METHOD AND SYSTEM OF SIGNAL PROCESSING USING UNCERTAINTY SET WITH ADJUSTABLE BOUND

摘要

A method for processing signals using an uncertainty set with adjustable bound includes a step of obtaining a signal subspace or an estimation of a signal subspace using a signal received in a sensor array; a step of calculating the minimum distance between vectors and an initial estimated steering vector on the signal subspace or the estimation of the signal subspace; a step of determining the bound of an uncertainty set about a weighted vector based on the minimum distance; a step of obtaining the uncertainty set about a target steering vector using the bound; a step of obtaining the weighted vector based on the uncertainty set; and a step of producing the output of the sensor array about the received signal using the weighted vector.
