[Discuss-gnuradio] Ideas for Clock Synchronization at Receiver in Spread Spectrum Implementation on Gnuradio

[Murtuza]

Hi friends,

I am working on implementing DSSS on gnuradio. I have a question regarding the clock sync techniques for a receiver. 
Can someone suggest me something that can be useful to me. I have an idea (its still an idea...not concrete yet ). 

I am thinking of using a barker code sequence initially to synchronize the clock instead of the gold code sequence that I use to spread the actual data. The barker code can initially work as the training sequence to get a lock on the clock. I would like to know how one can implement a synchronizing technique in gnuradio. I looked at the M&M algorithm used in the code gr_clock_recovery_mm_XX.c but found it rather difficult to understand. If possible will someone throw some light over it. 

Thanks
Ali
