One more thing - I know the approximate fundamental and partial
frequencies. Does that make my problem easier?

I could say no better than Robert, except that...

>> Any help is greatly appreciated.

If for some reason you really don't want to dig into the Wavetable
Synthesis 101, you should google for Prony, Pisarenko, MUSIC and ESPRIT
, or so called "high resolution" spectrum estimation methods. As you
guessed, they mostly have a relation with autocovariance. They're quite
math-intensive as well...

Cheers,

Pierre
