Document Type and Number:
Japanese Patent JP4163659
Kind Code:
B2
Abstract:
A wireless transmitting device includes a first and a second antennas (Tx1, Tx2), a first and a second transmitters (204A - 205A, 204B - 205B) connected to the first and the second antenna, respectively, signal provide unit (202 - 203) provide a short preamble sequence, a first and a second signal fields to the first transmitter, and provide an AGC preamble sequence, a data and a long-preamble sequence to estimate a channel response to the first and the second transmitters, and a controller (201) to power on the transmitters (204A - 205A, 204B - 205B) at different timings, respectively.
