Hi,
I managed to get the gnuradio example flowgraphs. However I'm getting
the following parser error when opening it: Start tag expected, '<' not
found
A snipshot of the error is attached.
May I know if there is any way to solve this issue?
Thank you,
Grace

Hi Jeff,
Thank you for the replies.
Do you mean that the sample rate for RRC taps should be 32 instead
of nfilts? I've set nfilts as a variable with the value of 32.
Regarding the deprecated packet encoder block, I've searched up a
bit but could not find much information on replacing the block. Came
across this:
https://dsp.stackexchange.com/questions/56163/gnu-radio-packet-encoder-decoder-unwanted-bytes-added-to-the-transmitted-str
but I downloaded the binary installers for GNURadio on windows and
can't find the example flowgraphs stated. Is there any way to access
these flow graphs or any examples on going about doing the encoding
and decoding?
Thank you.

The RRC taps have a sample rate of 32 and the grc file shows
samp_rate set to nfilts.

Hi all,
I'm trying to pass a text file through with a simulated
channel model modulated with BPSK. I'm having an issue
with not getting any data written on to the text file at
the file sink.
I passed a txt file in with file source block, followed
by packet encoder then modulate it with BPSK before
passing through the channel model. After that, I used
polyphase clock sync, CMA equalizer and costa loop to
minimise frequency, noise and time offset and
distortion. Finally I proceeded to use constellation
decoder, differential decoder, unpack K bits and packet
decoder before passing it to file sink.
The exact flow graph can be found on GitHub here:

Are there steps that I've missed out or done wrongly?
Please advise
Thank you,
Grace
