Hi Nemanja,
Thanks for your kind reply! I'm trying to design a program which will achieve the same result as the default benchmark, because I'll use the default benchmark in some part of the program too. So I use the default threshold 12. I want to make sure that is means that in the 8 Byte access code, at maximum 12 bits can be wrong for gnuradio to "find the pkt". Is this correct? Specifically, I defined a list 'ac' which is exactly the 64-bit access code. And then compare each of the received 64-bit data with the relevant bit in ac. If they match more than 64-12=52 bits, one packet is found. But the test result is that using this code will always find more than the n_rcvd number of packets in default benchmark. (in benchmark, n_rcvd is the total number of packets found). Looking forward to your further suggestions! Thanks a lot!

If you specify threshold of k bits, then it will output 0x3 every time it finds pattern that differs from given preamble at max. k bits. Maybe you can provide some more information. In my designs I usually use threshold 0. Best Nemanja On Wed, Jun 19, 2013 at 10:21 PM, yeran <address@hidden> wrote:
