A generalized maximum likelihood symbol synchronization scheme is proposed. It enables use of variable fractional-delay (interpolation) filters when the desired sampling rate conversion factor is non-integer or time varying. Furthermore, both IIR and FIR type variable filter structures can be used in efficient configurations. The paper includes both performance analysis and discussion of implementation complexity.
