Re: [Discuss-gnuradio] Polyphase clock sync ccf symbols needed ?

[Sam mite]

Can somebody comment on it please ? Thanks

Hi list,

I want to calculate the number of symbols taken by my *Polyphase clock sync
ccf block* after which it locks. Although I am getting 0 BER (except at
start) but I want to know after how many symbols loop get lock. And then by
varying different parameters I want to observe the lock time/symbols
needed.   From which plot I can get this information and how? . Current
parameters set are:

Sample/symbpol= 4
Loop BW= pi/100
damp factor= 0.707
filter size = 32
output sps = 1
max rate dev = 1.5
initial_phase=16

Phase plot is showing some sinusoidal output. Attached are the two phase
plots. phase2.jpg is zoomed in version of phase1.jpg.

Thanks ahead of time.
