Receiver, Transmission Device And Receiving Method

Abstract

An adaptive array antenna part receiving a plurality of transmitted signals in which subcarrier signal components of predetermined values is suppressed before transmission in order to distinguish a plurality of transmission antenna, by means of the plurality of transmission antennas; a part calculating weight factors suppressing the subcarrier signal components set in the predetermined, values, among sub-carrier components included in a received signal; and a part applying the weight factors to the adaptive array antenna means and receiving the plurality of transmitted signals with distinguishing the same are provided.

1 . A receiver comprising:
 an adaptive array antenna part configured to receive, by a plurality of transmission antennas or transmission beams, a plurality of transmitted signals in which sub-carrier signal components of given values are suppressed before transmission in order to distinguish the plurality of transmission antennas or transmission beams;   a part configured to calculate weight factors suppressing the sub-carrier signal components set in the given values, among sub-carrier components included in a received signal; and   a part configured to apply the weight factors to the adaptive array antenna part and receive the plurality of transmitted signals with distinguishing the plurality of transmitted signals.   
     
     
         2 . The receiver as claimed in  claim 1 , wherein: the given values are substantially zeros. 
     
     
         3 . The receiver as claimed in  claim 1 , wherein:
 the signal received by the adaptive array antenna part comprises signals transmitted from the plurality of transmission antennas or transmission beams simultaneously at a same frequency.   
     
     
         4 . A receiving method comprising:
 transmitting signals simultaneously from at least one transmission antenna other than a certain transmission antenna;   calculating weight factors suppressing all the sub-carrier components of signals received by an adaptive array antenna; and   applying the weighing factors to the adaptive array antenna and receiving the signals transmitted from the certain transmission antenna.
