A fine timing method is provided. The method comprises: calculating values of a first timing metric function based on cross-correlation between a received signal and M training sequences within a time period, to obtain a plurality of sets of X values spaced according to a certain pattern; calculating summations for the plurality of sets of X values, respectively; and determining the beginning of a data frame based on the calculated summations.

Fine timing

A filter bank for signal decomposition is provided. The filter bank comprises a plurality of filter units each of which has one input and two outputs forming two paths whose transfer functions are complementary to each other, where the plurality of filter units are connected to form a tree structure.

Transformation between time domain and frequency domain based on nearly orthogonal filter banks

A coarse timing method for a communication system is provided. The coarse timing method may include: calculating timing metric values for received signal samples using a self-correlation based timing metric function; calculating average timing metric values based on previous timing metric values; and determining whether there is a data frame based on the timing metric values and the average timing metric values.
