I am trying to extract data from a Turbo Code signal. My block’s input is the
signal with synchro sequences between frames. The block processes this input
in order to drop FEC bytes and send only useful data on the ouput. The
problem is I need a complete frame to process data correctly so any

Thanks a lot Martin.
Ok, now I can regulate the datastream, but one big problem has appeared.
How do I know when the last item of an inputstream is handled in the
general_work-function?
This is necessary because I want to add after the last item some bytes
and the number of incoming items is a
Hi Holger,
The input of my signal block is a bytestream b. The output should
also be a bytestream, but with a different number of outgoing items(not a
multiple of b).
In other words, after the transformation of the inputstream some extra-bytes
have to be appended.
For example:
Input y Bytes
Hello,
I am new in GNU Radio and could need some help. I want to implement some signal
processing blocks for data encoding/decoding. I read the "How to Write a Signal
Processing Block"-Tutorial and have understand most of that.
I have already build some blocks on myself and they work fine. But now
