    Abstract: The noise amount information storage unit 161 stores noise amount information which indicates relationships between gain value of the variable gain amplification units 121 and 125 and the amount of noise included in BB signals output from the down converters 131 and 135. The AGC unit 140 controls the gain value of the variable gain amplification units 121 and 125 so that the power of BB signals output from the down converters 131 and 135 becomes constant. The noise amount estimation unit 162 estimates noise amount of noise corresponding to the controlled gain value of the variable gain amplification units 121 and 125 by referring to the noise amount information stored in the noise amount information storage unit 161. The weight generation unit 170 generates weight matrix based on results of estimations performed by the channel characteristic estimation unit 150 and the noise estimation unit 162.

    Abstract: At a time T131, a wireless communication apparatus 11A determines to transmit a data packet, and then performs interference signal detection for a period TA. At a time T132 preceding a time T133 at which the period TA has elapsed since the time T131, the wireless communication apparatus 11A detects a data packet d21 (an interference signal). At a time T134 at which a period TB has elapsed since the time T132 at which the interference signal has been detected, the wireless communication apparatus 11A starts transmitting a data packet d11 to a wireless communication apparatus 12A. At a time T136, the wireless communication apparatus 11A completes the transmission of the data packet d11.

    Abstract: The present invention provides a wireless transmission system in which it is possible to exert a maximum path diversity effect even if the maximum number of effective branches is limited to a small number. A transmission timing control section (23) determines a transmission start timing to be a timing obtained by delaying a reference timing by a predetermined delay amount. A modulation section (21) modulates a signal by a modulation scheme such that an anti-multipath property is exerted when the signal is demodulated on a receiver side, and transmits the modulated signal at the transmission start timing. In a receiving station (12), a demodulation section (33) demodulates the receive signal to obtain receive data. The predetermined delay amount is such that signals are received at the receiving station (12) at a plurality of signal-receiving timings, and the number of signal-receiving timings is less than or equal to a predetermined maximum number of effective branches, a difference between the signal-receiving timings is greater than or equal to a predetermined delay resolution and is less than or equal to a predetermined maximum delay.
