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
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
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
