Frame Timing and Carrier Frequency Recovery for Frequency Selective Signals
A method and apparatus is provided for rapid frame/symbol timing and carrier frequency synchronization of a digital receiver to an orthogonal frequency division multiplexing (OFDM) signal and other transmissions (either continuous or burst) over a frequency-selective (wideband) channel. The method makes use of the autocorrelation and cross- correlation properties of one training symbol, having two or more identical parts. Its timing estimation performance approaches the ideal with a very low mean square error while its frequency accuracy is competitive when compared with conventional methods. It also has a wide frequency estimation range of half the signal bandwidth, yet it has a low, scalable and adaptive complexity that can be optimized to any specific application.
