Demodulate Noisy 16-APSK Signal

Apply 16-APSK modulation to a signal of random data. Pass the modulated signal through an AWGN channel. Demodulate the noisy 16-APSK signal. Check the bit error rate (BER).

Open the slex_16apsk_mod model.

Run the model with the EbN0 of the AWGN channel block set to 6 dB. The results are saved to the base workspace variable ErrorVec in a 1-by-3 row vector. The first element contains the BER.

With EbN0 set to 6 dB, BER: 0.164

Change the EbN0 of the AWGN channel block to 10 dB. Run the model and observe the decrease in BER.

With EbN0 set to 10 dB, BER: 0.012
