A wireless transmission apparatus that improves throughput in a wireless communication network system. In this apparatus, MT units of transmission/reception sections (122-1 to 122-MT) respectively correspond to MT units of antennas (121-1 to 121-MT) and transmit a preamble signal and a data signal via corresponding antennas (121-1 to 121-MT). MT units of transmission/reception sections (122-1 to 122-MT) use subcarriers allocated per antennas (121-1 to 121-MT) out of subcarriers (141, 142, 143 and 144) in preamble signal transmission. Furthermore, MT units of transmission/reception section (122-1 to 122-MT) use a subcarrier (140) having a frequency different from subcarriers (141, 142, 143 and 144) in data signal transmission.
