Abstract
Disclosed is a method for low voltage broadband power line carrier communication; when transmitting a physical layer protocol frame, short preambles are first transmitted to undergo automatic gain control, channel estimation, coarse-grained frequency offset compensation, and symbol synchronization; and then long preambles are transmitted to undergo automatic gain control, channel estimation, fine-grained frequency offset compensation, and symbol synchronization. Compared with the scheme of only transmitting long preambles, the present disclosure combines transmissions of short preambles and long preambles, which thus may quickly and accurately implement frequency offset compensation, automatic gain control, symbol synchronization, and channel estimation without sacrifice of precision, thereby achieving quick convergence, reducing resource overheads and time overheads, and enhancing system performance.
