Abstract
An apparatus provides burst and timing synchronization of an input signal used for high-rate indoor wireless communication, comprising. A burst synchronizer (20) is arranged to detect the onset of a burst of the input signal and provides an onset indicator. A frequency offset corrector (12) is arranged to correct the frequency offset between adjacent preamble sequences of frames within the burst of the input signal based on the onset indicator and provides a frequency offset corrected signal. A timing synchronizer (30) is arranged to detect the timing of first symbol of first frame of the frequency offset corrected signal, and provides a timing indicator. An equalizer (40) is arranged to remove inter-symbol interference from the frequency offset corrected signal based on the timing indicator.
