Method for synchronization of carrier phase pilot assisted.

摘要

Process for providing a synchronization pilot aided phase of a digital input signal comprised of signal samples Z (k) where k represents the symbol index, said signal comprising signal fields compounds of Ls symbols, namely a block of Lp pilot symbols Zp (k) and a data field of (Ls-Lp) data symbols Zd (k) and characterized by comprising for each field signal with a slot index l: - calculating a phase estimation corrected pilot f (P) (l) - initiation f (P) (l) of a first loop digital phase locked (DPLLF) that implements an algorithm for phase estimation and calculates a phase trajectory forward from signals the data symbols Zd (k) of the data field, said forward phase trajectory comprised of Ls-Lp forward phase estimates F (ks) being, ks being an integer ranging between 1 and LS- Lp on the data field of said signal field c on intervalol index; - initiation f (P) (l) a second loop digital phase locked (DPLLB), which implements an algorithm for phase estimation and calculates a phase trajectory backward from the signals of the data symbols Zd (k) where ks an integer ranging between Ls-Lp and one of the data field of said signal field with slot index l, said phase trajectory being comprised backward Ls-Lp phase estimates back B (ks). - combination of said paths to obtain a combined phase trajectory comprised of phase estimates (ks) between said phase trajectories forward and backward and a phase correction calculation example (ks).
