Frequency offset correction when decoding a packet encoded in a frequency modulated signal. Different symbols encoded in the packet may be corrected by different frequency offsets. In an embodiment, the frequency modulated signal is received on one of the signals of a multi-carrier signal (e.g., based on Orthogonal Frequency Domain Multiplexing, OFDM) and each packet is encoded according to 802.11(a) having the same long sequence repeating multiple times in a header portion. The repetitive sequence is used to compute the different offsets for different symbols.
