There is provided a wireless communication apparatus including: a matrix estimating unit that estimates a channel matrix of N rows and M columns (N and M are natural numbers); a selecting unit that selects S rows (S is a natural number, and S<min(M, N)) from the channel matrix estimated by the matrix estimating unit and generates a sub-channel matrix of S rows and M columns; and an arithmetic unit that calculates an antenna weighting coefficient matrix based on the sub-channel matrix generated by the selecting unit. The selecting unit selects the S rows that make the size of the sub-channel matrix to be the maximum from all matrices having S rows which are selected from the channel matrix.
