Abstract:
Interference in preamble signals and pilot signals in cooperative transmission using interference suppressing technology is avoided. A wireless apparatus for transmitting a wireless signal on which directivity control has been performed to stations in a wireless system including at least one wireless apparatus is provided with a known signal generating unit which generates a known signal to be added to the wireless signal, a weighting processing unit which performs weighting on the known signal generated by the known signal generating unit, and a wireless processing unit which transmits the known signal on which the weighting has been performed by the weighting processing unit.

Claim (Index 10):
A wireless apparatus that is provided in a wireless system and transmits a wireless signal on which spatial division multiplexing has been performed to a first receiving station configured in accordance with a first standard and a second receiving station configured in accordance with a second standard that is earlier than the first standard, the wireless apparatus comprising:\n a known signal generating unit that generates a known signal that includes L-STF; a weight calculating unit that calculates weight coefficients for subcarriers other than a pilot subcarrier signal based on propagation channel information provided from the first receiving station and propagation channel information provided from the second receiving station; a weight interpolating unit that interpolates weight coefficients for the pilot subcarrier signal based on the weight coefficients calculated by the weight calculating unit; a weighting processing unit that performs weighting on an input signal that includes L-LTF and signals that follow the L-LTF and include the pilot subcarrier signal based on the weight coefficients for the pilot subcarrier signal interpolated by the weight interpolating unit and the weight coefficients for the subcarriers other than the pilot subcarrier signal calculated by the weight calculating unit; and a wireless processing unit that transmits a transmission signal obtained by attaching the known signal to the input signal on which the weighting has been performed by the weighting processing unit.
