Abstract
A method for estimating symbol timing of a guard interval in an orthogonal frequency division multiplexing receiver of a wireless local area network comprises receiving a preamble including a plurality of short training symbols; sampling said short training symbols of said preamble at a first rate; correlating a first short training symbol with a second short training symbol that is adjacent to said first short training symbol and generating a correlation signal; normalizing said correlation signal to generate a normalized correlation signal; and calculating a mean absolute difference of said normalized correlation signal.
