A transmission system employs a quaternary amplitude modulation with waveforms
where A = 1 V and hTx(t) = rect(t/T ) is a rectangular pulse with duration T = 16 ns. By considering a channel with AWGN noise having PSD determine:
a) The incorrect transition probabilities of the inner numerical channel by assuming an optimum receiver.
b) The bit error probability when the bit mapping is
c) The bit error probability when the bit mapping is
Which of the two bit mappings is more appropriate?
