Abstract
An Orthogonal Frequency Division Multiplexing (OFDM) synchronization module includes a window generator module, a symbol timing estimator module, and a reliability metric calculator. The window generator module generates a sampling window that bounds a plurality of samples of OFDM symbols. The symbol timing estimator module generates an estimated symbol timing from the plurality of samples before a fast Fourier transform operation is performed on the plurality of samples. The reliability metric calculator calculates a reliability metric for the estimated symbol timing based on the estimated symbol timing. The window generator module changes at least one parameter of the sampling window based on the reliability metric.
