    Abstract
    By extending the space-alternating generalised expectation-maximisation (SAGE) parameter estimation algorithm to include a novel cost variant process, the robustness of direction of arrival (DoA) estimation from the SAGE algorithm is shown to improve. A novel extension to the standard SAGE algorithm that enhances the parameter estimation process is first introduced. Field trials that have been conducted using an adaptive antenna to verify the performance of this algorithm are presented. Results show that the extended SAGE algorithm improves DoA performance compared to standard SAGE by 5°, when operating in an urban environment.
