Wireless Communication Device, Control Circuit, Storage Medium, And Signal Processing Method

Abstract: A wireless communication device (100) which receives signals by using a plurality of receiving antennas (101-1, 101-2) in a wireless communication system which adopts multi-station simultaneous transmission, the wireless communication device (100) comprising: a synchronization processing unit (103) for estimating channel information on the basis of a known symbol sequence that is different for each base station antenna included in a received signal, and outputting a channel information estimation result; a channel matrix extension unit (105) for extending, on the basis of the channel information estimation result and an encoding rule of the received signal, a dimension of a channel matrix, and performing channel matrix extension processing of extending an array degree of freedom; an interference suppression weight generation unit (106) for generating an interference suppression weight for suppressing an interference signal by using the channel matrix subjected to the channel matrix extension processing; and an interference suppression weight multiplication unit (107) for extending a dimension of a received signal vector by using a result of observation in multiple-symbol time, multiplying the received signal vector, the dimension of which has been extended, by the interference suppression weight, and suppressing the interference signal.
