    摘要： A communication system includes communication protocols that allow a single network or multiple neighboring networks to increase resource sharing and reduce mutual interference and increase their overall throughput. Various protocols apply to homogenous networks in which all power line communication (PLC) devices of multiple networks are interoperable with respect to full power line communication in a common PHY and to heterogeneous networks having non-interoperable PLC networks which do not employ a common PHY. As to heterogeneous networks, a protocol herein enables coexistence via a special signaling scheme. In homogeneous networks, all nodes can communicate with each other using a common PHY, so that information about one PLC network can be transferred to another PLC network. In heterogeneous networks, not all PLC networks can exchange information using their own native PHY.

    摘要： A medium access control method is provided in which a control station transmits one specific frame to terminal stations, thereby arranging a schedule of a data transmission time of the control station and each of the terminal stations and allowing a time zone unused by a station for data transmission to be allocated to another station. The control station transmits a schedule frame having defined therein a time occupied by each of the terminal stations, thereby reducing overhead. Also, the completion of the preceding communication performed by another station is detected, thereby effectively using an idle time of a medium and improving transmission efficiency.

    摘要： A transmitting/receiving apparatus includes a packet construction section for dividing continuous data into a plurality of subpackets, and constructing a packet by concatenating the plurality of subpackets; a modulation transmission section for modulating the constructed packet, and transmitting the modulated packet to another apparatus; a training session execution section for checking channel conditions, when a predetermined condition is satisfied, and changing a modulation rule; and a subpacket transmission confirmation section for confirming whether or not a subpacket included in the transmitted packet is transmitted successfully to the transmission destination apparatus. If the modulation rule is changed by the training session execution section, the packet construction section reconstructs a new packet by concatenating a subpacket, which is confirmed as an unsuccessfully-transmitted subpacket, with subpackets newly generated from the continuous data, and the modulation transmission section modulates the reconstructed new packet, and transmits the modulated packet.

    摘要： Transmitter 2 includes inverse multicarrier transformer 23 and D/A converter 24. Inverse multicarrier transformer 23 generates a notch by masking a carrier at a frequency location predetermined in accordance with a communication method of the transmitter. D/A converter 24 performs a D/A conversion on a transmission signal containing the notch and transmits the signal to a transmission line. Receiver 1 includes power measurement unit 171, comparator 172 and coexistence signal determination unit 173. Power measurement unit 171 measures a power value of a signal input from the transmission line. Comparator 172 determines whether or not the notch exits by comparing the measured power value with a threshold. Coexistence method determination unit 173 determines the type of coexistence method, based on the location of the detected notch.
