Timing Synchronization of the WIND-FLEX OFDM Prototype
نویسندگان
چکیده
Timing synchronization of an early WIND-FLEX prototype is discussed in this paper. Simulation results for different low-complexity timing synchronization metrics are given in an AWGN (additive white Gaussian noise) channel. Simulations take into account frame detection via a threshold comparison followed by symbol timing estimation using a maximum search. Training symbols are fixed. A novel low-complexity metric reaches equal or better results than the maximum correlation (MC) metric, if we require optimal timing. Furthermore, nearly identical performance as with the maximum normalized correlation (MNC) metric is achieved, if threshold 0.4 or 0.6 is used.
