Method and apparatus for joint packet detection and radio frequency (RF) pulse synchronization in a super-regenerative receiver (SRR)

摘要

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.

1. A method of increasing a performance of a super-regenerative receiver (SRR), the method comprising:
initialize a quench rate to be greater than or equal to 2 based on a parameter; comparing a decision metric to a lower threshold value, the decision metric established from a first receiver operating characteristic (ROC); estimating a phase offset, using an over-quench method, and aligning quench signals at the quench rate of 1; comparing the decision metric to a higher threshold value to minimize a false alarm probability; confirming packet detection and the phase offset, using the over-quench method; aligning the quench signals based on the confirmed phase offset; determining whether a start frame delimiter (SFD) is detected after aligning the quench signals based on the confirmed phase offset; and detecting a payload in response to the SFD being determined to be detected.
