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. You'll probably find them in /usr/share/gnuradio/examples/digital/packet.
