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.

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. -- Cinaed On 1/7/19 11:22 PM, Thomas Lavarenne wrote: > Oh, it is "File Sink" not "Tagged file sink", didn't see sorry. > > Le mar. 8 janv. 2019 à 08:20, Thomas Lavarenne > <address@hidden <mailto:address@hidden>> a écrit : > > > > Hi, > > But, the issue is that correlate access code-tag block is not > working and producing tags, so that my output file will come > blank. as I am certain that at the output of FEC extended > decoder, both the sync bits and payload is available which I > have seen by attaching file sink at the output of FEC extended > decoder. > > > There is a block "Tag Debug" to see if the tag is generated behind > "correlate access code - tag block". > > On the other hand, the documentation of "Tagged File sink" indicate > that the block need the keyword "burst" (with value: True) to > trigger the saving of the data. > > Best regards, > > Thomas > > _______________________________________________ > > Discuss-gnuradio mailing list > address@hidden <mailto:address@hidden> > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > > > _______________________________________________ > Discuss-gnuradio mailing list > address@hidden > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list address@hidden https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
