Claim 3:
4. The system of claim 3, wherein the determining the plurality of updated RF PRFs by joining any two adjacent segments of the plurality of segments with the bridging PRF acceleration that is lower than or equal to the limit of PRF acceleration includes:
identifying one or more valley segments from the plurality of segments, wherein for each of the one or more valley segments, the segment PRF of the valley segment is less than the segment PRFs of valley adjacent segments of the valley segment, the valley adjacent segments and the valley segment being three consecutive segments in the forward window with the valley segment in the middle;
processing the one or more valley segments based on the one or more segment PRFs corresponding to the one or more valley segments, the limit of PRF acceleration, and the minimum duration of an RF PRF;
identifying one or more intermediate segments from the plurality of segments, wherein for each of the one or more intermediate segments, the segment PRF of the intermediate segment is less than the segment PRF of only one of one or more intermediate adjacent segments of the intermediate segment, the one or more intermediate adjacent segments and the intermediate segment being three consecutive segments in the forward window with the intermediate segment in the middle or two consecutive segments in the forward window;
processing the one or more intermediate segments based on the one or more segment PRFs of the one or more intermediate segments, the limit of PRF acceleration, and the minimum duration of an RF PRF;
determining a plurality of envelopes based on the one or more processed valley segments and the one or more processed intermediate segments; and
determining the plurality of updated RF PRFs by joining any two adjacent envelopes of the plurality of envelopes with the bridging PRF acceleration that is lower than or equal to the limit of PRF acceleration.
