摘要：
The wireless communication devices A and B determine the optimal diversity combining weight information that optimizes a diversity reception state at each antenna group A1, A2, . . . , AP through two-way training signal transfer between the wireless communication devices A and B. This optimal diversity combining weight information is set to each antenna of each antenna group A1, A2, . . . , AP. Wireless communication units A′, B′ perform spacial mapping of signals from antenna group A1, A2, . . . , AP using MIMO technology. Communication area can be enlarged by hierarchization MIMO using the optimal diversity combining weight information.
