- Using QPSK for modulation, add a turbo encoder and decoder to your transceiver and plot the simulated BER as a function of Eb/N0 for the AWGN channel. Discuss the results.
- Increase the number of iterations in the turbo decoder (use two additional values). Plot on the same figure the BER curve for each value. Comment on the results.
- Replace the turbo coder by an LDPC coder. Plot the BER and comment on the results. You must justify your choice for the LDPC coder.
- LTE uses a turbo coder as a channel coder. However, the 3GPP RAN1 group has recommended using LDPC codes for data channels and polar codes for signaling (i.e., for the control channels) for 5G systems. Research the literature to explain this decision. What is your personal view on this recommendation? Your answer must not exceed 1000 words.
