Edwin,
sorry, that TX flowgraph is a total untidy mess. I counted the <block>
tags, and there were 90, and most of them were disabled, but cluttering
the canvas. I didn't even bother to open the RX.
If you want people to assess your flowgraphs, you'll have to reduce them
to only contain what is relevant to the problem, and tidy them up to be
as clear as possible. Everything less would be a waste of your own time!
Reducing a problem to the minimum is actually a *necessary* step in
solving it.
Best regards,
Marcus

Hi,
I implemented a simple BPSK system. I ran simulation in GNURadio with
no channel effect added. Some of the received packets look weird. The
first attachment shows three received packet. They are supposed to be
identical. However, the second one suffers from ISI and a phase change.
I also attached my grc files. Could someone take a look at it and help
me figure out the cause please? Thank you very much!
Regards,
Edwin
