摘要： A wireless station capable of increasing the probability that a path diversity effect can be obtained in a case where a plurality of wireless stations transmit packets using a modulation/demodulation scheme with an anti-multipath property. A delay amount determining section (48) randomly selects a delay amount from among a plurality of candidate values. A transmission timing control section (47) determines a transmission start timing, at which to start the packet transmission, to be a timing obtained by delaying a reference timing by the delay amount selected by the delay amount determining section. At the transmission start timing, a modulation section (49) transmits the packet via an RF section (42) and an antenna (41).

摘要： A data transmitting and receiving apparatus is disclosed. The receiving apparatus receives a spread spectrum signal prepared by modulating a carrier wave with data to produce a data modulated signal and multiplying the data modulated signal with a spreading signal which has a bandwidth greater than that of the data modulated signal. The receiving apparatus may include three bandpass filters for passing three different band portions of a full band of the spread spectrum signal and producing an intermediate signal, and a detector for detecting data from the intermediate signal and for producing a detector output. The apparatus may also include a reception state evaluation device for detecting the current reception state of the detector and for producing a poor reception signal, when the detector is in a poor reception state. The poor reception signal is used for changing from a current band to another band.

摘要： 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.
