Hi Sakthivel,
The parameters I'm using in the PFB are:
samp_per_sym = 8
nfilts = 16
Samples/Symbol = 8
Loop Bandwidth = 1
Taps = firdes.root_raised_cosine(nfilts, nfilts,
1.0/float(samp_per_sym), 0.35, 11*samp_per_sym*nfilts)
Filter size = nfilts
Initial phase = nfilts/2
Maximum rate deviation = 0.05
Output SPS = 1
Regards,
Daniel.
