Claim 3:
4. A wireless communication method comprising: performing single carrier MIMO transmission between a transmitting station device and a receiving station device, in a wireless communication system, the transmitting station performing:
time-domain linear equalization processing for removing inter-symbol interference and inter-stream interference from a data signal to be transmitted to the receiving station device;
propagation path characteristics estimation processing for receiving a training signal which is transmitted by the receiving station device and estimating a transfer function matrix of propagation path characteristics;
filter tap calculation processing for calculating filter tap coefficients for the time-domain linear equalization processing based on the transfer function matrix by a predefined approach; and
transmission mode determination processing for calculating the filter tap coefficients by the filter tap calculation processing when the transfer function matrix meets a predefined condition, and for changing a transmission mode and determining the transmission mode that meets the predefined condition when the transfer function matrix does not meet the predefined condition, and
the receiving station device performing:
training signal generation processing for generating the training signal for use in estimation of propagation path characteristics and transmitting the training signal to the transmitting station device.
