Hello, I'm trying to detect the start of a frame after demodulation. To do this, I'm using the 'correlate access code - tag' block. I want a tag to be placed at the end of the prbs used to frame sync so subsequent blocks can process the packet.
I'm attaching a screenshot of a test I'm doing with the block. I can't get it to work. In the screenshot, I am appending a 32 bit long sync frame to 320 bits of data for the correlate block to detect. When I make the data all 0's, the correlate block detects nothing adding no tags to the stream. If I make the data random, tags are added at points in the stream which are not equal to the access code. What am I doing wrong or how do I use this block correctly? Thanks, Rich
