摘要： A radio communication method is capable of easily realizing multi-access in an ad-hoc network using a directive radio wave. In the ad-hoc network using the directive radio wave of the method, two PNC functioning as master devices are arranged opposed to each other so that their directivities face to each other. A super frame is time-divided into two sub super frames so that one of the sub super frames is controlled by one of the PNC and the other sub super frame is controlled by the other PNC.

摘要： Provided is a radio communication method capable of easily realizing multi-access in an ad-hoc network using a directive radio wave. In the ad-hoc network using the directive radio wave of the method, two PNC (A1, A2) functioning as master devices are arranged to oppose to each other so that their directivities face to each other. A super frame 200 is time-divided into two sub super frames (201, 202) so that one of the sub super frames is controlled by one (A1) of the PNC and the other sub super frame is controlled by the other PNC (A2).

摘要： Provided is a radio communication method which can reduce the power consumption as compared to the conventional technique while realizing coexistence of a plurality of radio communication methods and can perform synchronization with a super frame of other radio communication device. The super frame has life confirmation slots (2820, 2830) through which radio communication devices of various modulation types should transmit tone signals. A radio communication device has a chance to judge whether one or more radio communication devices using a different modulation type exist or no such device exists in the vicinity. If no such device exists, the slot to be used by the radio communication device of the modulation method is reported as a time that can be used by a radio communication group of other modulation method. Thus, by confirming existence of an object in the vicinity by other radio communication device with which communication cannot be performed, communication can be performed by sharing the super frame.

摘要： Provided is a radio communication method capable of optimally using the wide-band communication enabled time while maintaining power saving in an ad hoc network. According to this method, in the ad hoc network using the wide-band communication and a narrow-band communication, transmission and output of the narrow-band synchronization tone signal and the resynchronization tone signal are controlled so that the reach radius of the narrow-band synchronization signal and the resynchronization tone signal exceeds the reach radius of the wide-band signal (milli-wave UWB signal). Thus, when radio communication devices pass by each other, super frame synchronization is completed before reaching the wide-band communication enabled range of the ad hoc network, thereby optimally using the wide-band communication-enabled time.

摘要： A wireless communication method, a radio transmitter apparatus and a radio receiver apparatus wherein a signal sequence, which is used in a reception process using a first modulation scheme and can be generated from a signal sequence prepared for a reception process and used in a second modulation scheme, is employed, thereby achieving a performance to a similar extent to the reception process performance using the second modulation scheme. A radio transmitter apparatus (20) uses a first modulation scheme (e.g., OOK modulation scheme) to sequentially transmit, as a first sequence, both a sub-sequence a1(n), which is identical with a second sequence a(n) designed for use in a second modulation scheme (e.g., BPSK modulation scheme), and a sub-sequence a2(n), the bits of which are reverse to those of the second sequence a(n), in a time division manner. A radio receiver apparatus (30) detects the sub-sequence a1(n) and sub-sequence a2(n) in a received signal to send the detection result to the following stage for a signal processing.

摘要： There is disclosed a wireless communication apparatus that does not interrupt synchronous communication but can continuously perform the synchronous communication even when an address duplication occurs between the local wireless communication apparatus and a nearby wireless communication apparatus. A plurality of wireless communication apparatuses constitutes an ad hoc network system where they transmit beacons to each other. In the wireless communication apparatus, an address processing part (145) generates a first address, which includes a beacon period slot number corresponding to the position-on-beacon-period of a beacon generated by the local wireless communication apparatus, and a second address assigned at random. A beacon processing part (140) determines whether the second address generated by the address processing part (145) is coincident with a second address at another wireless communication apparatus. A transmitting part (170) uses one of the first and second addresses generated by the address processing part (145) to transmit a frame to the other wireless communication apparatus.

摘要： A beacon slot position control section of a radio communication apparatus constituting a radio network system which detects whether empty beacon slots are present in a beacon period. When an empty beacon slot is present before the period in which the radio communication apparatus transmits a beacon, a movable counter starts counting a specified number of super frames. When the count is completed, the radio communication apparatus transmits a beacon of the radio communication apparatus at the earlier empty beacon slot. Consequently, since the empty beacon slots are eliminated and the beacon period is compacted, even if the number of radio communication apparatuses joining the radio network system fluctuates dynamically, the radio communication apparatus can perform radio communication with high efficiency and less waste of consumed electricity.
