Abstract:

Synchronization of orthogonal frequency-division multiplexed OFDM signals is significantly more difficult than synchronization of a single-carrier system. The recently approved IEEE Standard 802,1 ig specifies a packet-based OFDM system that provides a basis for the discussion of OFDM synchronization in a packet-based enviwnment. Algorithms that synchronize the receiver canier demodulation frequency and phase, the data flame, the OFDM symbol timing, and the data symbol timing are discussed and analyzed in an AWGN channel. System View simulation is used to implement the flame and carrier frequency synchronization algorithms, where the pertonance of these algonthms is analyzed and they are shown to be useful detection algorithms for Standard 802.1 ig sig- nal reception.
