    摘要： An object of the present invention is to provide a reliable power-line carrier communications system having a resistance to high-level impulse noise synchronized with power-cycle frequency in virtue of redundancy on both time and frequency axes. An interleave part (11) shuffles, in n interleaving ways, transmitting symbols in a unit of symbol stream of the same length as a noise cycle. A modulation part (12) modulates the n-type symbol streams with n-piece carriers. A demodulation part (22) extracts amplitude/phase information from each of the n-piece carriers, and then outputs the information as amplitude/phase information streams. A de-interleave part (23) unshuffles the amplitude/phase information streams. A determination part (24) determines a symbol value from amplitude/phase information values in the same timing in the amplitude/phase information streams, and then outputs the values in a receiving symbol stream.

    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： To use high noise transmission lines, such as an electric wire, as the lines to transmit signals, it is imperative to reduce the level of signals. The present invention is provided with a sending signal generating means 10, which outputs converted data after converting an input signal into a plurality of carrier signals assuming values at such intervals on the axis of frequency that the frequencies may not interfere with each other. If an interfering noise with any one of the plurality of frequencies arises on the transmission line, removal of only a carrier of the noise frequency would leave the communication in a good condition. Furthermore, better results can be hoped for if the respective carrier signals are so arranged as not to interfere with each other or so arranged to intersect orthogonally with each other not only on the axis of frequency but also on the axis of time

    摘要： A highly reliable and high-speed data transmission is made by using an FH or MFSK mode as suitably selected according to the usage of channels. When a reception signal is entered into a receiver through a transmission line, (i) a signal processing unit supplies the spectrum intensity values of carrier frequencies, (ii) a channel detection unit controls the phase of a time slot based on the spectrum intensity values, selects the MFSK or FH modulation mode, and supplies reception code data corresponding to detected carrier frequencies, and (iii) a decoder supplies reception information data based on the reception code data. When transmission information data are entered into a transmitter, (i) a coding unit supplies, according to the selected modulation mode, transmission code data based on the transmission information data, (ii) a channel generation unit supplies, based on the transmission code data, carrier frequencies to be used and (iii) a waveform generation unit supplies a transmission signal to a transmission line.
