Weight coefficient calculation apparatus, adaptive array reception apparatus, and weight coefficient calculation method

摘要

PROBLEM TO BE SOLVED: To provide a weight coefficient calculation device, an adaptive array reception device, and a weight coefficient calculation method which can obtain large interference suppression effect.SOLUTION: A weight coefficient calculation device 1 includes a first weight coefficient calculation part for calculating a first weight coefficient on the basis of a received desired signal and a reception signal containing an interference signal, and a second weight coefficient calculation part for calculating a second weight coefficient to be applied to a reception signal, using the first weight coefficient as an initial value. The first weight coefficient calculation part may calculate the first weight coefficient also by using a first algorithm. The second weight coefficient calculation part may calculate the second weight coefficient also by using a second algorithm.
