摘要： A frequency band is divided into N subchannels. Sub-channels are first allocated for a power line communication system having a higher priority, such as public communication or the like. Sub-channels for a power line communication system 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 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： 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.

摘要： Provided is a communication apparatus which prevents, when two or more communication systems share a single communication medium in a time-division manner, an occurrence of situation where only a particular communication system suffers an influence of noise synchronizing with an AC power supply cycle or a half cycle thereof. When the communication systems share a single communication medium 121 in a time-division manner, a communication control section 209 determines a coexistence communication period, which is cyclically allocated to the communication systems, to be N×M+A (N: arbitrary integer, M: half cycle of an AC power supply cycle, A: arbitrary offset value which is not an integral multiple of the half cycle of the AC power supply cycle). A synchronization signal transmission/reception section 212 transmits and receives a synchronization signal to and from a communication apparatus belonging to another communication system so as to synchronize with the communication apparatus.

摘要： A communication apparatus and a method are provided for easily enabling two communication systems having different communication schemes and using the same communication medium to coexist. An access coexistence signal for notifying an in-home communication system 110 and 130 of the presence of an access communication system 120, and an in-home coexistence signal for sharing frequency and time resources between a plurality of in-home communication systems 110 and 130, are used. Further, by transmitting the two coexistence signals asynchronously, a process of synchronizing the access communication system 120 and the in-home communication system 110 and 130 is no longer required.
