This flowgraph can be downloaded from [[Media:Pkt_rcv_gr38.grc]]. For GNU Radio version 3.8 there is one difference:the Linear Equalizer and Adaptive Algorithm object are not available, the LMS DD Equalizer block is used instead.
The output of the Map block is the received bit stream. The 'Correlate Access Code - Tag Stream' block searches for the given access code by slicing the soft decision symbol inputs. Once found, it expects the following 32 samples to contain a header that includes the frame length (16 bits for the length, repeated). It decodes the header to get the frame length in order to set up the the tagged stream key information.
The remaining blocks operate as in the simulation example above.
