Phase-crosstalk Patents (Class 386/274)
  • Synchronization of signals transmitted over power lines
    Patent number: 11973350
    Abstract: A transmitter having: an oscillator to generate a clock signal and synthesize frequencies for modulating a message to generate first signals to a first direct current power line, and a control circuit to adjust timing of the first signals in synchronization with second signals transmitted in a second direct current power line disposed in a vicinity of the first direct current power line, by synchronizing phase of the first and second signals or by transmitting the first and the second signals in separate time windows.

  • Mitigating next interference
    Patent number: 11848722
    Abstract: A method to mitigate near end cross talk (NEXT) interference in networks may include receiving, through NEXT interference, a synchronization signal from a reference master node of a first network at a neighbor master node of a neighbor network. The method may also include scheduling, based on the synchronization signal, a cycle of downstream and upstream communications in the neighbor network synchronized with a cycle of downstream and upstream communications scheduled in the first network.
