Thanks for replying. The question is, how do I do this? We both agree the zeros need to go. What I'm not sure on is how to do that. I'd rather keep this contained to GRC, because I don't like maintaining python files not connected to grc. Can you explain how you do this or provide an example?

Since GRC parameters can be Python expressions, you can use formulas to do this.

If 'seq' is the original sequence to be modulated, use 'seq+seq' in the parameter to the modulate_vector variable block.

If the variable is named 'mod_vec', use:

mod_vec[len(mod_vec)/2:]

...as the taps for the correlation estimator.
