| Abstract: |
In this study, a novel concept, i.e. the tuneable sigmoid cyclic correlation, is proposed, and a relative estimator, named the generalised sigmoid cyclic cross‐ambiguity function, is also derived to deal with impulsive noise and co‐channel interference. Based on these concepts, a robust joint estimation method for time delay and Doppler frequency shift is proposed as well. Both theoretical analysis and simulations demonstrate the superior performances of the proposed approach over other existing methods, especially under strong impulsive noise. [ABSTRACT FROM AUTHOR] |
