The optimization problem of sampling synchronization efficiency in the process of power line communication is studied in this paper. An optimization strategy of calculating the synchronous position is proposed. A bit algorithm after the first piece is designed in accordance with the direct synchronization algorithm. The power line sampling is fulfilled in the process of on?chip sampling. The innovation of this paper is to use the biggest difference between high and low potentials in chip to calcu?late the displacement number in the on?chip. The sliding window was designed to calculate the on?line maximum offset. The test results show that the algorithm can increase the time efficiency by a factor of 40%.
