PROBLEM TO BE SOLVED: To obtain a wireless communication device in which degradation of communication quality is prevented even when a plurality of antennas are used and communication quality in synchronization acquisition is improved. SOLUTION: A wireless reception device that includes a plurality of antennas and performs demodulation, error correction and decoding includes Fourier transformers 7-1 and 7-2 which calculate a frequency signal that is obtained by performing the Fourier transform of a reception signal for each antenna, a covariance matrix calculation unit 8 which calculates a covariance matrix of the frequency signal for each antenna, a Cholesky decomposition unit 9 which performs Cholesky decomposition of the covariance matrix, and an inverse matrix multiplication unit 10 which multiplies the inverse matrix of the results of the Cholesky decomposition by the frequency signal, and performs demodulation, error correction and decoding to the multiplication results.
