Title: Method and system for a reference signal (RS) timing loop for OFDM symbol synchronization and tracking

Abstract: Aspects of a method and system for a reference signal (RS) timing loop for OFDM symbol synchronization and tracking may include tracking symbol timing in an Orthogonal Frequency Division Multiplexing (OFDM) signal based on at least a reference symbol set. A receiver timing may be adjusted based on at least the symbol timing. The symbol timing may be tracked by generating an output signal as a function of a guard time .DELTA.t.sub.g in a phase discrimination feedback loop. The reference symbol (RS) set may be generated in an RS extraction module or circuit, from at least a fast Fourier transform of the received OFDM signal. The receiver timing may be coarsely adjusted and then finely adjusted. The coarse receiver timing adjustment may be based on processing at least a primary synchronization signal and a secondary synchronization signal.
