  • tools for processing radio-signals

    Hi all,


    I do not know if this newsgroup is still alive.


    I would like to learn to do "offline" signal-processing on
    radio-signals. E.g. consider that I have a wav-file or an iq-file that contains a recording of POCSAG (paging) message.
    What tools r python libraries can I use to exact the POCSAG message from it?


    I know there are python packages like scipy and numpy which would help
    me a lot.

    But are there python packages that help
    - find the beginning of the packet in the audio/iq file.
    - find the beginning and the end of the sync-pattern
    - determine the exact frequency and/or any timing offset of the
    sync-pattern?




    If this would have been a continuous stream, I would have use GNU Radio
    for this.
    But I am interested in learning how one would do this with "offline".


    Thanks in advance!
