Abstract: A method to detect a packet includes: receiving an input sequence including preambles; detecting a transition from a noise period to a signal period in the input sequence; dynamically adjusting a gain of the input sequence in response to the signal period being initiated; and distinguishing an intended packet from other packets, among packets received in the preambles.

Abstract: Examples provide a method of performing automatic gain control (AGC) in a wireless receiver, the method including computing, by an energy detection (ED) circuit, a variance in an output signal of an analog-to-digital converter (ADC), and activating, by the ED circuit, an AGC circuit to adjust a gain of at least one component in a radio frequency integrated chip (RFIC) in response to the variance exceeding a threshold. Examples also provide for a wireless receiver that implements such a method.

Abstract: A method of increasing a performance of a super-regenerative receiver (SRR), includes initializing a quench rate to be greater than or equal to 2 based on a parameter, and comparing a decision metric to a lower threshold value, the decision metric established from a first receiver operating characteristic (ROC). The method further includes estimating a phase offset, using an over-quench method, and aligning quench signals at the quench rate of 1, and comparing the decision metric to a higher threshold value to minimize a false alarm probability. The method further includes confirming packet detection and the phase offset, using the over-quench method.
