Hello, I have updated Ubuntu version to 18.10 in order to install GNU radio version 3.7.12. (As GNU radio version 3.7.12 have bug fixes for additive CCSDS de scrambler, as per said by gr-satellites). but the different problem arises, when I have simulate(run) the same GRC flow graph file (the one with correlate access tag stream and fixed length packet tagger). I have attached the GRC file for your reference.As this file is run with generate option to NO GUI option, once I press the run button in GRC, it is not continuously run the flow graph and didnot get the output. can you please tell me, when am i dong wrong.

In order to get the flowchart to work - at least in the sense of filling up the output.txt file - I added a "Stream to Tagged Stream" block and define a consist tag to get the Tag Debug block to work.

Sorry, I didn't mean to imply you needed the stream to tagged stream block to make it work. I just put in at the beginning so I could use the tag debug as a brute force search to find out what was blocking the flow. There are two sequential tag blocks - the correlate correlate access code-tag from gnuradio and a block from gr-satellites - I would guess that is all you need.

Hello, I have seen those examples for packet_tx and packet_rx. but the issue here is I want to do contionous transmission and I think, header/payload demux block is for packet transmission, and besides, this block differentiate header and payload , and I want to do is to extract preamble(CCSDS syncbits-32 bits) from the contionous frame and receive only frame bits except syncbits. can you please give suggestion about this? and yes, It is great to see those examples from which i can get an idea about modulation/demodulation without the use of deprecated blocks.

That's the place where I'd start. You should drop *all* the blocks that are deprecated. As said, these are deprecated for a reason (buggy and no-one is willing or able to fix them – most of the ones you're using are simply broken on a conceptual level). Instead of the correlate access block, my guess is that the header_payload_demux-based examples from gr- digital/examples/packet/packet_rx.grc and packet_tx.grc and packet_loopback_hier.grc will make you much happier.

Re: [Discuss-gnuradio] Regarding correlate access code-tag block
Hello,
thanks for your guidance.
I have also attached the grc file, input/output files and python file for your
reference. after adding tag debug, still didn't get any output. I have also
tried this same in ubuntu 18.04 with GNU radio 3.7.11 version.
actually because these psk blocks are deprecated, I have tried it with dpsk
mod, demod block. But as I wanted to do continuous transmission, I didn't find
replaced block for correlate access code-tag block, and the cusom block from
gr-satellites are for extracting syncbits.
I have also tried with simple flow graph by just sream muxing 2 files one with
sync bits and other one is payload file and give that output to correlate
access code-tag block, but that also didn't work.
It would be grateful, If you guide me on this. I just want to make that sync
bits searching and extracting from payload and receive only payload at the
output.
With Best Regards,
Maitry Raval,

I broke down and looked at the image.
Note, PSK Demod, Correlate Access Code - Tag, Packet Encoder, and Packet
Decoder have been depreciated.
And they're usually depreciated because they have problems - and they
are usually replaced with different blocks which work better and are
typically more general.
The tutorials are good place to start looking for the replacements.

Re: [Discuss-gnuradio] query regarding wav file recording through wav file sink block
Hello, I am using USRP-B200 mini, and as I want to use USRP offline, that's why I am trying to record the transmitted modulated signal through UHD USRP source to some file, Is it ok to use .txt file for this? And the problem arise in this is , when the signal is being recorded in a wav file through wav file sink, then the recorded wav file's amplitude is lower than the the signal I have seen during simulation in time sink and FFt sink.

What USRP are you using? Also, the filename doesn't matter to its content at all, so this is fine, but using .txt for a file that contains raw binary samples is questionable. So, back to your original problem: can you describe how the result of the operation is different from what you're expecting? I still must admit I don't get where the problem lies.

Hello, Thanks for your response. My requirement is to use GNU generated wav file into MATLAB.

Re: Issue in file sink block
Hello, Adding some more information to the previous mail, that I want to use only receiver part from GNU radio and SDR and my transmitter is different from which I am transmitting modulated signal and received and demodulated using GNU radio. so, when I am doing simulation( using back to back blocks of constellation modulator with the demod blocks) I am receiving the 1100 and 1010 data same as transmitted. but , when I am using the receive only blocks and use external transmitter, then also received data changes. I don't understand , where is the main problem. Kindly help.

But when I am transmitting some random pattern instead of repetitive using file source, I am not receiving the same pattern, while I am converting the stored ASCII to binary using converter. I have sent the GRC file in previous mail. Kindly let me know, where is the problem? Waiting for your positive response.

Issue in file sink block
Hello , I am using GNU radio along with ADRV9361-Z7035 Board for data reception and demodulation. I have faced an issue of using file sink block along with QPSK demod blocks. when I am attaching dpsk/PSK demod block with file sink, I have not received data in binary format. it gives some trunk values. when I am doing wrong, please guide us. I have taken a reference of below link. [ https://courses.washington.edu/ee420/projects/lab2_gnuradio.pdf | https://courses.washington.edu/ee420/projects/lab2_gnuradio.pdf ] The only difference is that I am using receiving section only. as I am transmitting from other source. so I have attached fmcommsource block with dpsk demod followed by file sink.

Hello, I understand, I think, I need to use PSK demod using below link. https://wiki.gnuradio.org/index.php/Guided_Tutorial_PSK_Demodulation But, as I have a requirement of storing the demod data in file , how is it possible using file sink or any other way, please guide.
