Abstract
An adaptive control system includes a plurality of coupling circuits. Each of the coupling circuits is adapted to connect electrically a respective one of the electronic devices to the multi-carrier channel, and is operable to search for an idle frequency band of a multi-carrier channel and to enable the respective one of the electronic devices to communicate with a corresponding one of the electronic devices via the idle frequency band of the multi-carrier channel.
Claims10
An adaptive control system for operatively communicating a plurality of electronic devices through a multi-carrier channel having a plurality of frequency bands, at least one of the plurality of electronic devices communicating with at least another one of the plurality of electronic devices via an idle frequency band among the plurality of frequency bands, and said adaptive control system comprising:
- a plurality of coupling circuits adapted to connect electrically the plurality of electronic devices to the multi-carrier channel,
- wherein each of the plurality of coupling circuits includes a peak detector that is adapted to be connected electrically to the multi-carrier channel, and that is operable to determine the idle frequency band based on whether binary digital signals transmitted within the plurality of frequency bands are noise by determining if first two digits of most significant bit of each of the binary digital signals are zero.
An adaptive control method for operatively communicating a controlling device and a controlled device through a multi-carrier channel having a plurality of frequency bands, said method to be implemented using a coupling circuit which connects electrically the controlling device to the multi-carrier channel, said method comprising the following steps of:
- (a) searching, by the coupling circuit, for binary digital signals in the multi-carrier channel under one of the plurality of frequency bands;
- (b) determining, by a peak detector of the coupling circuit, whether the signals are noise by determining if first two digits of most significant bit of each of the binary digital signals are zero;
- (c) using the coupling circuit, determining that said one of the plurality of frequency bands is an idle frequency band when the determination made in step (b) is affirmative, and repeating steps (a) and (b) with another one of the plurality of frequency bands when otherwise;
- (d) using the coupling circuit, receiving a control signal from the controlling device and transmitting a signal associated with the control signal to the controlled device through the multi-carrier channel under the idle frequency band determined in step (c);
- and
- (e) enabling, by the coupling circuit, the controlling device to operatively communicate with the controlled device in response to receipt of a confirmation signal from the controlled device.
