Patent ID: 7804907

Claim:
A radio-frequency receiver device comprising: a plurality of antenna elements; and an adaptive processing portion for controlling weights to be given to respective received signals respectively received by said plurality of antenna elements, said adaptive processing portion includes: a plurality of frequency analyzing portions configured to convert the received signals received by said plurality of antenna elements into frequency signals; a plurality of characteristic extracting portions configured to extract characteristic signals indicative of characteristics of the received signals received by said plurality of antenna elements, on the basis of said frequency signals obtained by conversion from the received signals by said frequency analyzing portions; a plurality of weight calculating portions configured to calculate said weights to be respectively given to the received signals, solely on the basis of said characteristic signals extracted by said characteristic extracting portions; a plurality of inverse frequency analyzing portions configured to convert said weight calculated by said weight calculating portions, into timewise signals; a plurality of weight multiplying portions configured to multiply the received signals respectively received by said plurality of antenna elements, by said timewise signals obtained by conversion from said weights by said inverse frequency analyzing portions; and a signal combining portion configured to combine together the received signals multiplied by said timewise signals obtained by said weight multiplying portions, wherein said adaptive processing portion is configured to control said weights on the basis of said frequency signals obtained by conversion from said received signals by said frequency analyzing portions.
