Abstract: Techniques for quickly and accurately determining whether a channel is being used for transmission of data using one of a plurality of communications protocols for low power signals using random data of a packet are disclosed. The techniques increase sensitivity and reduce the false alarm rate for a wide range of signal and noise levels. A noise detection technique uses an adaptive window size for fast noise detection that increases the rate of scanning channels during a signal identification period.

Adaptive Zigbee symbol detection improves detection sensitivity beyond ?97 dBm. The techniques use a chip-based differential to generate frequency deviation samples for Zigbee detection or data filtering frequency deviation samples generated using sample-based differentials based on an oversampled received signal to improve the signal-to-noise ratio.

Abstract: An apparatus and method for performing a fast Fourier transform in the analog domain with passive components. A complex analog signal that is shift and scale invariant is derived from analog circuit properties. A butterfly circuit processes such signals using only passive components by mapping the Kirchhoff current and voltage laws into operations on the signals. A fast Fourier transform circuit of any desired width is constructed from such butterfly circuits. The passive networks require no power as the operations are on the presented signal; energy is taken from the source signal so no battery or power supply is needed. Thus, when the signal becomes quiescent, the power consumed is zero. Further there is no need of a clock or other timing device; rather, it is the operation of Kirchhoff laws in the network, which apply essentially upon arrival of the signal, that is made analogous to the desired operation.
