  • Method and apparatus for synchronizing a carrier frequency of an orthogonal frequency division multiplexing transmission system
    Patent number: 6219333
    Abstract: A system for synchronizing a carrier frequency of an orthogonal frequency division multiplexing (OFDM) transmission apparatus, even when a carrier frequency offset is above a frequency bandwidth of one subchannel. The synchronization of the carrier frequency in the OFDM transmission apparatus is accomplished by alternating between a coarse mode for synchronizing an integer part of the carrier frequency offset and a fine mode for synchronizing a prime part of the carrier frequency offset.
