Abstract:
1. A method for OFDM flame boundary detection in a vehicular multipath channel in which a sample including a plurality of OFDM data inputs is received by a receiver in a sampling period, the method comprising the steps of: (a) for each sample of a plurality of samples, applying long preamble local copy correlation (LP-LCC) to the sample data inputs to yield LP-LCC results, each LP-LCC result representing energy of a single path; (b) integrating the LP-LCC results to obtain a respective channel energy; (c) finding a maximal channel energy among the channel energies; and (d) using the maximal channel energy to detect a frame boundary; further comprising the step of performing a short preamble (SP) delayed cross correlation (DCC) on the sample data inputs to validate a respective LP-LCC result.
