Abstract
Embodiments of a method for OFDM frame boundary detection in a vehicular multipath channel include use of a maximal channel energy instead of a strongest path for detecting a frame boundary. A sample of OFDM data inputs is processed using long preamble local copy correlation and integration to obtain a channel energy which sums all paths of the multipath. A plurality of such channel energies obtained within a given time period are searched for a maximal channel energy, which, when found, is used to detect the frame boundary.
