Standards for access codes are interesti
Hi all,
The gr_correlate_access_code_bb block takes a 64-bit access code as
input to detect the start of incoming frames using a hamming distance
with a threshold. The packet utilities has a default access code and
uses a threshold of 12.
I'm not sure who wrote the code and who picked the d
