Abstract
A data packet, comprising a preamble and the preamble comprising a plurality of synchronization bits, is received where the preamble may be of either a first preamble type or a second preamble type. Channel estimation is performed using at least a first portion of the plurality of synchronization bits. It is determined whether the preamble is of the first preamble type or of the second preamble type, where the determination overlaps in least in part with the channel estimation. The performance of the channel estimation is controlled such that: in the event it is determined the preamble is of the first preamble type, the performance of the channel estimation continues for a second portion of the plurality of synchronization bits, adjacent to the first portion of the plurality of synchronization bits, after the processing of the first portion of the plurality of synchronization bits; in the event it is determined the preamble is of the second preamble type, the performance of the channel estimation ends after processing the first portion of the plurality of synchronization bits.
