SUMMARY This paper mainly discusses the time-difference-of-arrival
(TDOA) estimation problem of digital modulation signal under impulsive
noise and cochannel interference environment. Since the conventional
TDOA estimation algorithms based on the second-order cyclic statistics
degenerated severely in impulsive noise and the TDOA estimation algorithms based on correntropy are out of work in cochannel interference,
a novel robust signal-selective algorithm based on the generalized cyclic
correntropy is proposed, which can suppress both impulsive noise and
cochannel interference. Theoretical derivation and simulation results
demonstrate the effectiveness and robustness of the proposed algorithm.
