Hi George - please don't send me private email - please keep the
discussion on the mailing list.
It's called Constellation Decoder or Receiver - depending - see the

Though I'm currently on a ThinkPad, I like Dell Latitude as well. I prefer their corporate line over XPS, mostly because if you break something, say a keyboard, they have service manuals and parts. https://www.dell.com/learn/us/en/70/campaigns/xps-vs-latitude-heaI bought my last Dell Latitude fro
Hi Noah,
As far as Ubuntu goes, before you purchase - check compatibility here:
https://certification.ubuntu.com/desktop
You might start out at 18.04 and try upgrading to see how things do, but if
it worked for 18.04 chances are you'll be okay on 20.04.
Pay close attention to the chipsets listed
The Dell XPS are really nice laptops. I'm using one right now, and I love
it. I'm running Ubuntu 20.04 and GNU Radio, and I got an Ettus USRP B210
and X310 connected up to it, and it's 100% solid. I definitely recommend
it. I'd also suggest that you run Ubuntu 20.04 to get all the latest

Hello,
I’m looking to buy a linux laptop specifically for gnuradio with pybombs.
Does anyone have specific hardware recommendations that work well or to
avoid? Similarly, is it safe to use the most recent version of Ubuntu
(20.04 LTS)? I’ve been mostly considering Dells because of their extensive
Hi George - use the search window near the top of the GUI near the right
hand side - third block in from the right. When you the mouse pointer
on it and should say "Search for a block by name (or key)" - then type
in your request.

Hi Kevin,
Thank you for your reply. Your simple method is what I am trying to do here.
However, I do not know how to prepend each message with a preamble of known
bytes in GNU Radio. Could you please elaborate on this? Did you mean that you
are doing this in Python? Is it with the embedded py

Hi Lannan:
I am working on a similar project in the digital not audio domain.
There are two approaches. The simple one, which I am currently using, is to
prepend each message with a preamble of known bytes. Then you recover byte
alignment from the received bitstream by using a sliding window
Hello,
Is there a constellation Demodulator that goes with the Constellation
Modulator in the Gnuradio blocks? Any suggestions on how to build one with
the available blocks?
Building it will be tricky because the available blocks would need to do
the signal processing that captures the correct sa
Hi Artur,
Thank you for your suggestions!
And yes, that’s exactly what I am doing. At the receiver, I have a
polyphase clock sync, CMA equalizer, and a costa loop to correct phase and
frequency offset.
I am using Adalm Pluto, which is looping back right now. I am able to align
Hello Lannan,
As far as I could understand, you want to do the following operations:
(i) Generate bytes -> (ii) Modulate -> (iii) Transmit -> (iv) Receive ->
(v) Demodulate -> (vi) Recover bytes
and then you want to align the byte sequences from steps (i) and (vi).
Am I correct?
What hardware (m
Hi everyone,
(It's me again.)
I am working on an audio channel using QPSK modulation. I currently am
transmitting through a signal source that outputs bytes. I am looking for a
method to align the byte boundaries so I am able to hear a clean audio at the
receiver.
Here is an idea of wha
This should be resolved now in the PPA for Ubuntu 20.04 - thanks to Paul
coming up with the correct naming structure for the package!
