Abstract:

In this paper we develop an adaptive beamsummer for direction of arrival DOA estimation of slow fading Raleigh signals, using a new design approach, termed Adaptive DetectionEstimation for specific Tasks ADEPT. For DOA estimation, the ADEPT method yields a weight adaptation criterion which is optimized for those weights that minimize the Cramer-Rao CR lower bound on achievable mean-square-error of any unbiased DOA estimator constructed on the beamsummer outputs. Simulation results are provided which show that the ADEPT DOA beamsummer yields DOA estimates whose mean-squared error MSE approaches that of the more complex maximum likelihood implementation.
