[Discuss-gnuradio] Syncronize a DSSS signal

[Mauro Bressan]

Dear all, 

I'm trying to syncronize  the receiving signal from a Direct Sequence Spread Spectrum.

I have to divide the receiving signal by the code sequence, and i thought to put a delay block (gr_delay) betwen the spreading code and the division operator. Then I want to set the delay with a close loop control using my output signal, but the problem is that I'm not able to refresh the delay value, it stay only at the initial value.

I've tryied also to change it with a slide bar, but when I'm going to change the value I find an error : TypeError: in method 'gr_delay_sptr_set_delay', argument 2 of type 'int'

How can I make it work? Or have you other ideas to syncronize the system?

Thank you all.
