Explore hands-on how a QPSK signal is generated and demodulated. Check the transmission spectrum for different pulse shapers. Vary further parameters like carrier frequency etc.
QPSK BER for AWGN channel
Explore the bit error rate for QPSK. Adjust Eb/N0 and measure the corresponding BER. Compare it to the analytical bit error probability. Vary the pulse shape - does it have effect on the BER?
QAM BER for AWGN channel
Analyse the bit error rate of M-QAM over an AWGN channel. Adjust Eb/N0 and the constellation size. Compare the measured BER to the analytical bit error probability.
QPSK BER - equivalent baseband (fast)
Measure the bit error rate for QPSK in high accuracy. Use this experiment to hands-on verify the analytical bit error probability as a function of Eb/N0. This app is optimized for high simulation speed.
