worth to disable the FLL (and give the
modem a signal for which the FLL is not needed) in order to see if the
FLL is indeed disturbing the Costas loop.

Dear Hervé and Dear Jean-Michel,
Congratulations and thank you for your efforts in expanding the knowledge base!
I've already requested the book to be added to the company's digital library.
Best of wishes,
Ceren

Hi all,
I'm using Symbol Sync from core GNU library. Although when Gardner TED is
selected, the parameters section **do not**have any option to define a slicer
constellation, the generated python file passes qpsk.base as slicer argument as
follows:
self.digital_symbol_sync_xx_0_0_0 = d
Hi Engin,
The phase is constant. You're observing a constant phase sinusoid in real-time
(using time sink) within a specified duration (which is determined by the
number of points parameter of time sink). The time sink graph gets updated in
real-time, hence the jitters seem to be happening.
Fo
Hi all,
This is my point of view on the issue:
15M sample rate is equal to 960M bits/sec data transmission from your USB port
to your SDR device. 960M = 15M samples * 32 bits/sample (lime sdr sink/source
working with 32 bit float) * 2 (because Inphase and Quadrature assuming you're

Hi all,
First off, thank you for all the amazing work you've put into this community.
I'm working with 1.024M baud QPSK signal with sample rate of 4.096M. This
symbol sync block works perfectly 99% of time. I can successfully demodulate
input symbols, perform convolutional decoding and find syn
