TECHIQUES FOR TIME-DOMAIN FRAME SYNCHRONIZATION OF PACKETS

摘要

A technique for frame synchronization in a communication system includes performing symbol correlation on received signal samples. A determination is made as to whether a magnitude of the symbol correlation is greater than a first threshold. In response to the magnitude of the symbol correlation being greater than the first threshold, an indication is provided that the received symbol is a valid symbol (e.g., a SYNCP symbol or SYNCM symbol). In response to the magnitude of the symbol correlation being less than the first threshold, an indication is provided that the received symbol is an indeterminate symbol (e.g., an invalid symbol or a SYNCM/2 symbol).

1. A method of frame synchronization in a communication system, comprising:
performing, using a preamble detector, symbol correlation on received signal samples; determining, using the preamble detector, whether a magnitude of the symbol correlation is greater than a first threshold; in response to the magnitude of the symbol correlation being greater than the first threshold, indicating, using the preamble detector, the received symbol is a valid symbol; and in response to the magnitude of the symbol correlation being less than the first threshold, indicating, using the preamble detector, the received symbol is an indeterminate symbol.
