PROBLEM TO BE SOLVED: To provide an OFDM transmission beam forming method corresponding to pilot arrangement or GI in such a way that a receiver can rightly estimate a delay profile. SOLUTION: A communication apparatus comprises: a plurality of reception weight calculating means each for calculating a reception weight to multiply each sub-carrier to which a reception signal is assigned, for each of a plurality of antennas using each communication path estimation value; a plurality of reception weight profile calculating means each for converting each reception weight into data on a time axis to calculate a time profile of the reception weight; a plurality of transmission weight profile calculating means each for generating a time profile of a transmission weight by segmenting a partial phase from the time profile of each reception weight; and a plurality of transmission weight calculating means each for calculating the transmission weight to multiply each sub-carrier to which a transmission signal is assigned, for each of the plurality of antennas by converting the time profile of the transmission weight into data on a frequency axis.
