Hi list,

Are all the obtained bursts.dat files useless when they are captured by unmodified burst_ind?When I use the standard burst_ind I obtain a chain of burst-files.I also sometime see displayed the word SACCH/8 on the log-screen. If one tries to single out burst-files belonging to SACCH/8 or TCH/F would these be useful as inputs to kraken after being converted to keystream?

Somewhere on this list I read that captured data must be converted to the MAC-block,if one looks for frames, and that code could be found in airprobe .What ist the meaning of that? Aren't the MAC-block alreday displayed when using burst_ind?

regards

erich

Emne: Content of burst data in burst_ind branch

Can you please clarify what kind of preprocessing has been done for bursts in burst_ind data?

Does TCH/F data come through with block-diagonal de-interleaved? Or does come as 8 interleaved bursts?

I think all the intra-burst de-interleaving has already been done at DSP level. Is this correct?
