It is EXTREMELY difficult to see how the fine grained control of transactional memory that is available with the full cell will be available with this "spe's hung on a Core 2". The first article even got it wrong, calling this a core 2 quad (from the remarks that followed right after calling i

[Discuss-gnuradio] choosing start of frame bits, studies?

2008-01-11 Thread George Nychis
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

Hi, I'm an italian student and I'm working on OFDM system of GNUradio Implementation. I have a problem. I'm a couple using RFX2400 to transmit a data stream but I can't receive anything. I checked the frequency offset and I found that the frequency offset is about 10-15 kHz. I think this value is v
