摘要： A wireless transmitting device for use in communication with a wireless receiving device with a wireless packet, includes a plurality of antennas, and a signal generator to generate a signal for a wireless packet to be transmitted. The wireless packet includes an automatic gain control (AGC) preamble sequence and data transmitted by using a plurality of subcarries from the plurality of antennas. The AGC preamble sequence includes a frequency component in which a value at a time “t” of a signal in a time domain of the AGC preamble sequence transmitted from an iTx-th antenna (where iTx=1, 2, 3, . . . ) is different for each of the antennas.

摘要： A receiver/transceiver includes N pieces of receiving antennas, a propagation path characterization estimator, a weight generator for interference canceller, an array processing interference canceller, a weight generator for signal estimator, a signal estimator, a transmission signal classification apparatus, and a decoding order decision apparatus. The antenna inference elimination circuit eliminates only signal component relating to transmission signal component which does not belong to groups. The signal estimator performs separation and decoding of the transmission signal belonging to the group. The transmission signal classification apparatus classifies the transmission signals from sets of the transmission antennas in which a cross-correlation value of the vector is larger than a threshold value, into one group, and classifies the transmission signal in which the cross-correlation value is smaller than the threshold value, into another group.
