SYSTEM AND METHOD FOR DETECTING AND PROCESSING RECEIVED SIGNAL WITH PULSE SEQUENCE

摘要

Methods of detecting a pulse sequence in a received signal are disclosed, each of which entails operating on samples of the received signal. One method entails determining a correlation of samples with a reference sequence, and detecting the pulse sequence based on the correlation. Another method entails selecting a reference sample associated with a pulse, and detecting the pulse sequence by analyzing samples based on one or more lengths of a time hopping interval and the reference sample. Another method entails selecting a reference sample associated with non-restricted time hopping intervals, and detecting the pulse sequence by analyzing samples that are based on substantially one or more lengths of a half pulse interval and the reference sample. Further, disclosed is a method of determining a timing drift by selecting samples, determining a time delay between the selected samples, and determining the timing drift based on the determined time delay and an expected time delay.
