Greetings,
Ok, got this. After some test's i think that the problem is with my
descrambler (de-interleaver and Viterbi seems to be ok). Currently, im using
Matlab's one provided by comm. toolbox.
Is it correct to use 127-bit length pre-defined scrambling/descrambling seq?
(i found it in 802.11 standard). Or it sould be only implemented as a shift
register with poly 1+x4+x7?
And last one question:
In any of frames generated by your grc script, there sould be 16x"0" in
SERVICE field (as it a part of PLCP Header) - becouse a typical wlan card is
able to decode it, it is following the 802.11 standard - am I right?
Best,
Ernest
