Method and system for an OFDM joint timing and frequency tracking system

Abstract

Aspects of a method and system for an OFDM joint timing and frequency tracking system may include tracking carrier frequency and symbol timing in an Orthogonal Frequency Division Multiplexing (OFDM) signal based on at least a reference symbol set. A receiver frequency and timing may be adjusted based on the tracked carrier frequency and symbol timing. The carrier frequency may be tracked by generating an output signal as a function of a frequency offset Δƒ, and the symbol timing may be tracked by generating an output signal as a function of a guard time Δtg. The received OFDM signal may be fast Fourier transformed to generate the reference symbol (RS) set. The receiver frequency and timing may be adjusted coarsely prior to fine adjustment. The coarse receiver frequency and the timing adjustment may be based on processing a primary synchronization signal and a secondary synchronization signal.
