Abstract:
1. A method of processing a signal, comprising: receiving the signal; generating samples of the received signal; and detecting a quasi-periodic pulse sequence in the received signal by analyzing the samples of the received signal, wherein the quasi-periodic pulse sequence is based on a substantially periodic pulse sequence having an associated pulse period, wherein the quasi-periodic pulse sequence comprises: a plurality of adjacent pulses each separated from each other by the pulse period and one or more adjacent pulses separated from each other by twice the pulse period, wherein only a single pulse of the adjacent pulses resides in each interval of periodic pulse intervals due to one or more pulses having been deleted, and wherein the periodic pulse intervals have an associated second period greater than the associated pulse period of the substantially periodic pulse sequence, or a plurality of adjacent pulses each separated from each other by the pulse period and one or more adjacent pulses separated from each other by a defined amount less than the pulse period, wherein only a single pulse of the adjacent pulses resides in each interval of periodic pulse intervals due to one or more pulses having been deleted, and wherein the periodic pulse intervals have an associated second period less than the associated pulse period of the substantially periodic pulse sequence.
