  • Signal transceiving device and methods for detecting a synchronization point in a signal
    Patent number: 10243726
    Abstract: A signal transceiving device includes a transceiver and a microprocessor. The transceiver receives a signal from a power line. The microprocessor performs correlation calculation for the signal with a first predetermined pattern to obtain a plurality of first calculation results, performs correlation calculation for the signal with a second predetermined pattern to obtain a plurality of second calculation results, generates a plurality of weighting values according to the first calculation results and determines a position of a synchronization point in the signal according to the weighting values. When the weighting value corresponding to a sample point of the signal satisfies a first condition and the second calculation result corresponding to the sample point satisfies a second condition, the microprocessor determines to use the sample point as the synchronization point.
