[Discuss-gnuradio] access code detection threshold in benchmark tx/rx scripts

[Nowlan, Sean]

I'm trying to understand the benchmark receive path. The access code detection threshold is set to -1 in receive_path.py. After looking at the digital_correlate_access_code_bb block, it appears the INT32 threshold, -1, is being compared with the *UINT32* Hamming distance between the known code and the received code. If I'm not mistaken, C/C++ will do unsigned comparison and therefore *any* number of errors < UINT32_MAX (2^32 - 1) will be accepted. Am I reading this incorrectly?
