Subject: | Empty file at File Sink for BPSK mod&demod simulation |
Date: | Wed, 24 Jun 2020 18:36:21 +0800 |
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: https://github.com/wei1006/HAB
Are there steps that I've missed out or done wrongly?
Please advise
Thank you,
Grace
