No coding SQR COS-Filter with = 0.5
PRBS9 data sequence
Pulse width and oversampling 32
Length 100 symbols
Symbolclock 10 kHz.
Make the corresponding settings on the demodulator. Synchronize
to a bit sequence, satrting with the 9
th
symbol, 12 bits long, result
lenght 80 symbols.
Attention: The mappings of the DUT and the demodulator have to
correspond!
Select the vector representation on the demodulator.
The symbols should be located in a square grid.
Select Impairment State On on the R&S SMV03.
The symbols must no longer be arranged at right angles; the Y
axis should be inclined towards the left by 10 °, with a setting of -
10 ° it should be inclined towards the right.
