PROBLEM TO BE SOLVED: To suppress the deterioration of a transmission characteristic in beam forming without increasing an operational amount. SOLUTION: A radio communication apparatus for performing transmission beam forming includes: a receiving means (101) for receiving the estimation value of a propagation response; a calculating means (103) for calculating a weight matrix to be used for the transmission beam forming, based on the estimation value; a correcting means (104) for correcting a partial component among the components of the weight matrix; and beam forming means (106, 107-1 to 107-M, 108-1 to 108-M) for performing beam forming by the weight matrix corrected by the correcting means, and performing radio transmission.
