Hi Rohith - if you post a copy of your GRC file - not an image of the GRC file - then someone on the list should be able to help you. Also, I noticed you're trying to use the RRC with excess bandwidth - typically excessive bandwidth requires raising  the sampling rate. And at the risk of over

Hello Cinaed, I’ve not experienced this problem with Gnuradio you describe, but in another context, spacecraft communication, we had a simple test setup that transmitted a fixed pattern of alternating ones and zeros. However the way error coding was done the lock was always poor. For testin

Hi Rohith - Ihe minim sampling rate  for the Pluto is in the ball park of 500 KHz. See https://ez.analog.com/adieducation/university-program/f/q-a/557730/pluto-sdr-sampling-rate -- Cinaed On 11/30/22 05:54, Rohith Rajan wrote: I am asking a doubt regarding receiver using an  Adalm Pluto SD

I am asking a doubt regarding receiver using an Adalm Pluto SDR In the receiver section we are using *Polyphase Clock Sync*, *Linear Equalizer* and *Costas Loop.* My doubt is that is the configuration parameters of these blocks are dependent on the BW of the signal(Sample Rate) Keeping the parame
