    摘要: An energy efficient radio having a clocking system utilizing two clocks with very different precision and power characteristics. In another aspect, the time that a radio spends on listening/receiving is optimized so that energy is not wasted when there is no need to keep receiving. In another aspect, to further improve the energy efficiency, two receive portions with drastic difference in power consumption, instead of a single receive portion as is used in a typical wireless receiver, and are used to process different parts of a received packet.

    摘要: Local clock modeling for a discrete event simulator is described. A local clock generator provides realistic clock characteristics in terms of clock precision and clock drift and clock mapping utilities provide API for other modules and/or protocols in the discrete event simulator to schedule events on local clocks instead of global clock of the simulator.

    摘要: Methods, systems and apparatuses for dynamic spectrum access by both primary users (PUs) and secondary users (SUs) are disclosed. In one embodiment, a method for communicating over a channel may include obtaining, at a secondary transmitter, first and second signals intended for a primary receiver and secondary receivers, respectively; generating, at the secondary transmitter, an assist signal based, at least in part, on the obtained first signal; generating, at the secondary transmitter, a data signal based, at least in part, on the obtained second signal; determining, at the secondary transmitter, a power split ratio between the data signal and the assist signal based, at least in part, on any of a power and a signal-to-noise ratio of the first signal; and generating, at the secondary transmitter, a third signal comprising (i) the data signal and (ii) the assist signal in accordance with power split ratio.
