CHANNEL LENGTH ESTIMATION AND ACCURATE FFT WINDOW PLACEMENT FOR HIGH-MOBILITY OFDM RECEIVERS IN SINGLE FREQUENCY NETWORKS

A method of estimating a channel length (304) in a wireless receiver is disclosed. The receiver receives a signal (122) from a remote transmitter. The receiver selects a plurality (K) of different candidate channel lengths and determines a respective criterion value (402) of the signal for each of the plurality of different candidate channel lengths. The receiver selects a channel length (410) from the plurality of different candidate channel lengths in response to the respective criterion value (404).
