In addition to lobes compensation and diversity reception with a single group of a plurality of auxiliary antennas

摘要

PURPOSE: To eliminate an interference wave without increasing number of auxiiliary antennas and to simultaneously obtain the diversity effect with respect to a desired wave in the side lobe canceller. ;CONSTITUTION: An auxiliary antenna reception signal is branched and given to a 1st adaptive array 207 for eliminating an interference wave and a 2nd adaptive array 208 independently of the array 207, and at first a maximum ratio synthesis is implemented between a main antenna reception signal and a 2nd adaptive array output. The spatial diversity effect is obtained with respect to the desired wave through the processing. After diversity synthesis, a side lobe is cancelled by the 1st adaptive array 207 and its output is given to an adaptive equalizer 111. The 1st adaptive array 207 is usually subject to adaptive control by the Apfel Baum calculation or the like and the control by using correlation arithmetic operation using discrimination data being an adaptive equalizer output is implemented with respect to the 2nd adaptive array 208.;COPYRIGHT: (C)1994,JPO&Japio
