Claim:
1. A method of performing pulse synchronization in a super regenerative receiver (SRR), the method comprising: setting a quench rate of the SRR to a value of 1.5 times a chip rate of an incoming signal; acquiring an expected preamble sequence of an arbitrary sample set among a plurality of possible sample sets; acquiring an expected start frame delimiter (SFD) sequence for all of the possible sample sets to achieve frame synchronization; computing respective correlation metrics for bits of the expected SFD sequence while the expected SFD sequence is acquired for all of the possible sample sets; calculating a decision metric based on the correlation metrics in response to an SFD sequence being detected for one or more of the possible sample sets; and identifying a best sample set for demodulating the incoming signal among all of the possible sample sets based on the decision metric to achieve pulse synchronization.
