Abstract
A system and method estimates symbol timing of long training symbols and coarse carrier frequency offset in an orthogonal frequency division multiplexing receiver of a wireless local area network. The system and method estimates the symbol timing and coarse carrier frequency offset during short training symbols of a preamble of a data packet. Fine carrier frequency offset is estimated during long training symbols. Channel estimates during a data portion of the data packet are adapted.
