Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. The wireless communication method according to claim 4, wherein
the predefined approach is an approach that determines a transmit weight matrix W(z) with a product of 1/det(H(z)) and adj(H(z)) using a determinant det(H(z)) of a transfer function matrix H(z) for channel impulse response (CIR) and an adjugate matrix adj(H(z)),
the predefined condition is whether the determinant det(H(z)) of the transfer function matrix H(z) is in a minimum phase or not, and
changing of the transmission mode is changing of antenna combination including a multiplex factor of antennas of the transmitting station device and the receiving station device.
