Abstract:
1. A method of synchronizing to an ultra wideband signal and receiving a partially serialized, sequence keyed, ultra wideband symbol, comprising: a) operating a first plurality of oscillators, each one of the first plurality of oscillators selectively coupled to a respective one of a plurality of parallel receiver paths; b) maintaining a second plurality of oscillators in a non-operational low-power state; c) operating the plurality of parallel receiver paths; d) determining based at least in part upon an output of each of the plurality of parallel receiver paths, whether a synchronization sequence has been received; e) receiving a first portion of a partially serialized, sequence keyed, ultra wideband symbol; f) operating if the determination of d) is affirmative, a second plurality of oscillators; g) selectively coupling each one of the second plurality of oscillators to a respective one of the plurality of parallel receiver paths; and h) receiving a second portion of the partially serialized, sequence keyed, ultra wideband symbol, wherein each of the plurality of receiver paths receives an in-phase and quadrature version of the outputs of the oscillators coupled thereto, the method further comprising decoupling the first plurality of oscillators from the plurality of parallel receiver paths subsequent to receiving the first portion of a partially serialized, sequence keyed, ultra wideband symbol.
