Method and apparatus of triple-decoding for IEEE 802.11p physical layer mechanism

摘要

A method for receiving and storing a packet of symbols. The method decodes the packet of symbols using a first decoding algorithm, and if the first decoding algorithm fails to correctly decode the packet of symbols, then the method decodes the packet of symbols using a second decoding algorithm. If the second decoding algorithm fails to decode the packet of symbols, then a third decoding algorithm is used. The third decoding algorithm can be sub-packet decoding, where a first sub-packet is part of the packet of symbols. If the first sub-packet is decoded successfully, then the method generates a channel estimate using the properly decoded information, and then uses that channel estimate to decode a subsequent sub-packet using the channel estimate, where the second sub-packet is a set of symbols that are a portion of the packet of symbols.

1. A method for decoding symbols in a transmission signal, said method comprising:
receiving a packet of symbols; decoding the packet of symbols using a first decoding algorithm; determining that the first decoding algorithm failed to correctly decode the packet of symbols; decoding the failed packet of symbols using a second decoding algorithm; determining that the second decoding algorithm also failed to correctly decode the packet of symbols; and decoding the twice failed packet of symbols using a third decoding algorithm.
