摘要： A frequency band is divided into N subchannels. Sub-channels are first allocated for a power line communication system (A) having a higher priority, such as public communication or the like. Sub-channels for a power line communication system (B) having a relatively low priority, such as in-home communication or the like, are allocated from free subchannels. In this case, the subchannels used by the power line communication system (A) having the high priority are limited to a plurality of consecutive subchannels from an upper side or a lower side of the frequency band.

摘要： A power line communication apparatus transmits a signal to a first power line communication apparatus through a power line connecting to a second power line communication apparatus. The power line communication apparatus includes an information retriever for retrieving transmission rate information indicating both a first transmission rate and second transmission rate. The first transmission rate correspond to a first path of the power line along which the signal is directly transmitted to the first power line communication apparatus, and the second transmission rate corresponds to a second path of the power line along which the signal is transmitted through the second power line communication apparatus to the first power line communication apparatus. A selector selects, based on the transmission rate information, a path corresponding to a higher transmission rate among the first and second paths. A transmitter transmits the signal through the selected path.

摘要： In a multicarrier communication using a balanced transmission line such as a power line, a multicarrier communication method operable to select carriers on the basis of an SN-ratio and balancing of the transmission line is provided. Available carriers are selected in accordance with the balancing of the balanced transmission line, in which the balancing is measured at either a sending terminal or a receiving terminal or alternatively at both of them, and the SN-ratio measured between the sending terminal and the receiving terminal. More specifically, any frequency domain having poor balancing and a poor SN-ratio is treated as a non-carrier-employing domain, and consequently the available carriers are selected at other frequency domains. In addition, a modulation method having the greatest permissible multivalue is selected for each of the carriers. The carriers are selected in light of the SN-ratio and balancing, or alternatively in highest-to-lowest order of frequency. Transmission power is controlled for each of the carriers to suppress radiated emission. The SN-ratio and balancing are measured at predetermined time intervals to renew the selection of the carriers and the selection of the modulation methods.

摘要： There is provided a communication network system which can set communication parameters which enable an operation under a maximum possible communication rate in a situation where a transmission path has cyclic noise/impedance fluctuations, without being influenced by such local noise/impedance fluctuations. A transmission/reception apparatus 100 transmits training packets for checking the state of the power line at two distinct points in time. Each time a training packet is received, a transmission/reception apparatus 101 analyzes SNR at each carrier frequency, and stores an SNR evaluation result. The transmission/reception apparatus 101 compares two SNR evaluation results which are obtained through two instances of a channel estimation algorithm, selects an SNR evaluation result which dictates a faster PHY rate, and transmits it to the transmission/reception apparatus 100. The transmission/reception apparatus 100 changes modulation/demodulation rules based on the received SNR analytical result.

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.
