Abstract
Devices, methods, and other embodiments associated with phase based preamble detection are described. In one embodiment, an apparatus includes a wireless transceiver, an evaluation logic, and a configuration logic. The wireless transceiver receives a wireless signal from a wireless device. The wireless signal includes a preamble sequence. The evaluation logic evaluates the preamble sequence by comparing phases of the preamble sequence to phases of predefined preamble sequences to identify a matching preamble sequence. The comparison is done without using amplitude information. The configuration logic configures the wireless transceiver to synchronize wireless communications with the wireless device based, at least in part, on the matching preamble sequence.
