Abstract

For completely received and decoded network frames, a method for locating the start of a received signal, including storing an original waveform stream in a time-indexed buffer, reconstructing an ideal waveform based on the received packet, selecting and/or analyzing an optimal part of the reconstructed waveform, for use of the selected part in comparison with the previously stored original waveform, comparing the received (stored) and original (ideal) waveform or waveform representation, and optionally analyzing the results for use in TOA and/or TOAD calculation, signal quality analysis, AP time synchronization.
