Abstract
A wireless communication apparatusaccording to the present invention is provided with reception channel coefficient calculation units-to-for calculating reception channel coefficients of respective antennas, transmission channel coefficient calculation units-to-for calculating transmission channel coefficients of respective antennas by extrapolation based on variations of the reception channel coefficients, absolute value calculation units-to-for calculating absolute values of the transmission channel coefficients, a threshold calculation unitfor calculating a threshold based on the reception channel coefficients, comparison units-to-for comparing the absolute values and the threshold, and transmission channel coefficient correction units-to-, when the absolute values are greater than the threshold, for correcting the transmission channel coefficients so as to match the absolute values to the threshold.
