PLC device can be introduced into when attempting being communicated via power line network simultaneously.In general, being connected to power line network
HomePlug equipment is using the standard being defined by HomePlug Power line Alliance and other HomePlug devices exchange information.Similar
Ground, the G.HN equipment being connected to power line network uses defined G.HN standard and other G.HN devices exchange information.However,
G.HN equipment can not with HomePlug equipment communication, can not detect HomePlug equipment, with HomePlug equipment backward and
Hold.Therefore, in the communication period of G.HN equipment, HomePlug equipment may attempt to initiate communication.Similarly, set in HomePlug
Standby communication period G.HN equipment may attempt to initiate communication.This can lead to dry between HomePlug equipment and G.HN equipment
Disturb, defective communication simultaneously affects the performance of PLC device in power line network.
Above-mentioned incompatible in order to solve the problems, such as, power line network includes power line socket 104,106 and 108, electric lines of force

Data to be transmitted and can be from receiving extract respectively/processing data can be encapsulated further in selected header.Bimodulus G.HN
Equipment may be configured such that can detect HomePlug equipment and with HomePlug equipment backward compatibility.In other words, bimodulus
G.HN equipment is that the G.HN of compatible mechanism enabling to be communicated with G.HN equipment and incompatible HomePlug equipment is set
Standby.
Power line communication (PLC) equipment to operate generally according to " HomePlugAV " standard, and depending on this standard
Version, carries out PLC signal transmission using broadband (for example, from 1.8MHz to 30MHz, or up to 86MHz).However, should
PLC signal may interfere with (for example, to be penetrated in other communication equipments and application with operation in this PLC device identical frequency range
Frequency marking knows (RFID) application).In order to avoid from PLC signal transmission in the overlapping communication band being used by other communications applications
Interference, some subcarriers (or coherent sub-carrier group) of PLC frequency band can be excluded (or by trap) and not transmit PLC signal.
Currently, the subcarrier being excluded during the transmission in PLC signal can be come pre- based on PLC standard (for example, HomePlugAV standard)
Fixed.(according to PLC standard) does not allow these predetermined subcarrier of PLC device communication to be referred to herein as, and " static trap is secondary to be carried
Ripple ".For example, for PLC signal transmission, 10 subcarriers in PLC frequency band for the current HomePlug AV1.1 equipment are usually required that
In (" trap subcarrier " or " trap "), power spectral density is reduced at least 30dB.Due to the frequency characteristic of trap subcarrier, lead to
Often supplementary protection frequency band is adopted to require to meet trap on any edge of trap subcarrier.Correspondingly, it is adjacent to trap pair
One or more subcarriers (" adjacent subcarriers ") of carrier wave may not be available for transmitting (for example, due to guard band), by
This total throughout decreasing the quantity of subcarrier (for example, frequency resource) being available for transmitting and reducing PLC device.This
Outward, for be scheduled to the PLC signal that transmitted it may be difficult in frequency domain and time domain, the OFDM symbol being transmitted is carried out fixed
Shape, and maintain simultaneously guard band (in a frequency domain) and guard interval (in the time domain), make intersymbol interference (ISI) minimize and
Reach trap requirement.For example, the efficient trap in frequency domain leads to the ISI in time domain.However, time domain is reduced using guard interval
ISI can reduce the available time-domain resource amount being available for transmitting.Existing PLC device is generally using the time-domain windowed letter that band is overlapping
