Abstract
Wireless communication devices A and B perform wireless communication with the MIMO technology. The wireless communication devices A and B determine the optimal diversity combining information that optimizes a diversity reception state through a two-way training signal transfer. This determination can be made based on reception level information, baseband reception IQ information, correlation information between a diversity-combining received signal and a predetermined information sequence, or the like, which are obtained when the diversity combining information with respect to each antenna is sequentially changed. The optimal diversity combining information can be determined by receiving training frames or symbols (the number of antennas+1) times.
