Claim One:
1. An apparatus for wireless communication, comprising: a receiver configured to wirelessly receive, via a wireless local area network, a physical layer data unit comprising a preamble portion and a remainder portion, the preamble portion comprising a sequence configured to indicate a start of the physical layer data unit and the remainder portion comprising one or more interposed training fields that are interposed between a plurality of data symbols, wherein at least one of the one or more interposed training fields comprises a first training field including a channel estimation sequence, wherein at least one preceding data symbol of the plurality of data symbols precedes the one or more interposed training fields, and wherein one or more initial training fields precede the plurality of data symbols; and a processor configured to decode one or more of the plurality of data symbols based at least in part on the one or more interposed training fields, wherein the processor is configured to decode the at least one preceding data symbol based at least in part on at least one of the one or more initial training fields, and wherein the processor is configured to decode the at least one preceding data symbol again based at least in part on the at least one of the one or more interposed training fields if a difference between a channel estimate based on the at least one of the one or more initial training fields and a channel estimate based on the at least one of the one or more interposed training fields exceeds a first threshold.
