Abstract:
A method of detecting a collision between signal transmissions on a carrier medium in a network, the method including:transmitting a first identifier from a transmitter of a network device, the first identifier having a predetermined duration and including a pulse at a temporal location within the first identifier specific to the first identifier, the pulse comprising a multi-cycle waveform having a frequency of greater than 1.1 MHz; receiving a second identifier at a receiver of the network device, the second identifier having a predetermined duration and including a pulse at a temporal location within the second identifier; determining whether the temporal location of the pulse within the second identifier corresponds to the temporal location of the pulse within the first identifier; and if not, then detecting a collision on the network, wherein the transmitting includes propagating a multi-cycle square wave through a filter to generate the multi-cycle waveform.
