ABSTRACT:
A wireless transmitting device includes a first and a second antennas, a first and a second transmitters connected to the first and the second antenna, respectively, signal provide unit 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 to power on the transmitters at different timings, respectively.
