Ok. After couple of days trying to decode your frame i decided to check my
receiver with real samples.
Could it be possible that after demodulation (de-interleaving,
de-convolutional, de-scrambling) im getting over 40x0's in correct positions
(9 reserved bits, 16x0s in duration, correct pads) and still cant work out
your frames? Such amount of correct data couldnt be a coincidence :(
One last idea: If groups of bits are correct, then most likely you forgot to invert the pilot patter according to the sequence given in Equation 18-25 of the standard.
