摘要： In the case where there is a conflict over a band between communication stations that have reserved the band, the communication stations mediate and avoid the conflict of reservation use with low-load processing. In a wireless communication system, band reservation use is permitted, and a plurality of reservation types are provided according to priority of communication. A communication station that performs reservation use describes a reservation type and a rock-paper-scissors value in a beacon. When there occurs a conflict of reservation use at some area, reservation use having higher priority remains, and a communication station that has performed reservation use having a lower priority moves it to another area. In the case where there is a conflict between reservations having the same priority, the communication apparatuses that have performed reservation use perform control by rock-paper-scissors between themselves, and move the reservation of the apparatus that has lost by the judgment.

摘要： In network groups adjacent to each other constructed by communication apparatuses notifying beacons, the communication apparatuses can exchange necessary data between themselves, avoiding interference. Communication stations in a group set one beacon period to operate the network group. A communication station in the group acquires a beacon period and a reservation period of an adjacent group, sets its own reservation period avoiding the acquired beacon period and reservation period, and as necessary, enters the adjacent group to exchange necessary data. A device shared by a plurality of users does not belong to any group, and a communication apparatus in a different group temporarily enters the beacon period as necessary to exchange data.

摘要： Disclosed is a method that preferably performs transmission processing to a time sequence signal of a known pattern as the pre-amble and an OFDM transmitted signal. In data communications, the general practice defines the pre-amble and detects the peaks of the mutual correlation to thereby detect synchronization. The pre-amble here is defined by the binary value in most cases for simplification of a correlation detecting device. In this case, the spectrum becomes irregular with sharp peaks and dips, which deteriorates the correlation characteristic. The method of the invention forcibly adjusts the spectrum amplitude of the pre-amble pattern on the transmitting side while retaining the phase information thereof, and thereby the method improves the spectrum and correlation characteristics while securing simplification of a correlation detecting device on the receiving side.
