摘要 G3-PLC系统子载波数量较多导致前导符号的时域采样点较多,传统的基于互相关的同步算法应用于该系统时由于运算量过大而变得难以实现。文中根据G3-PLC前导序列的特点,提出了一种同步算法,以较小的性能损失为代价,将运算量降低两个数量级。该算法在FPGA中得到了实现。 The large number of subcarriers in G3-PLC system causes too many samples of preamble in time domain.Traditional synchronization algorithm based on cross-correlation needs large operations and is hard to realize when used in this system.According to the characteristic of preamble in G3-PLC,a new synchronization algorithm is put forward,which reduces the operation by two orders in magnitude with slight performance degradation.The algorithm is realized in FPGA.
