摘要

A first device is adapted to: receive a spread-spectrum timing-reference signal from a master device; detect a code-phase of the received reference signal; and transmit data to the master device with a timing that is defined relative to the detected code-phase. Also presented is a master device for receiving data transmitted by one or more first devices, the master device being adapted to generate and transmit a spread-spectrum timing-reference signal to the one or more first devices. Also presented is a power-line communications network comprising: a master device; and one or more first devices as discussed above.
