Abstract:
1. A radio receiving device which has a plurality of antennas and which extracts a desired signal by adaptive array processing, the device comprising: an adaptive array processor configured to estimate weights for said plurality of antennas using a predetermined type of array parameter, assign said estimated weights to reception signals received by said plurality of antennas, and combine the weighted reception signals to extract said desired signal; and an array parameter optimal value estimation unit configured to estimate an optimal value of said predetermined type of array parameter which optimizes the weight estimation performance of said adaptive array processor, wherein said array parameter optimal value estimation unit includes: a determination unit configured to determine a propagation environment of said reception signals; a storage unit configured to previously a table consisting of optimal values of the array parameter corresponding to different conditions of said propagation environment; and a table reference unit configured to refer to said table, thereby estimating an optimal value of said array parameter appropriate to the propagation environment of the reception signals determined by said determination unit.
