ABSTRACT:
Variable-length information-containing frames (e.g., MPDUs) are aggregated into a bitstream using frame delimiters to distinguish the frames. Aggregation and frame extraction techniques are provided that support recovery from bit errors that may be present in a frame delimiter. One class of techniques involves providing redundant length information in the frame delimiters, e.g., by using multiple copies of a length field or error correction codes usable to correct errors in the length field. The receiver can use the redundant information to detect and correct errors in the length field. Another receiver-side technique iteratively attempts to locate the end of the corresponding frame when a corrupt frame delimiter is detected. Conventional synchronization fields may be eliminated.
