Abstract
The present invention discloses a preamble sequence generating method and device, which are used to avoid a problem, caused by damages to a preamble sequence resulting from interference in an NB-PLC system, that it is difficult for a receive end to correctly perform timing synchronization. The method includes: determining a quantity m of orthogonal frequency division multiplexing OFDM symbols that constitute a single pattern in a preamble sequence, where m is not less than 2; and generating a preamble sequence according to m, so that every m OFDM symbols that are in the generated preamble sequence and consecutive in a time domain constitute a single pattern, and the generated preamble sequence includes at least two patterns, where the patterns are different from each other. Embodiments of the present invention further provide a timing synchronization method and device.
