Bit error analysis for digital communication

below the link is my module...

i found some difficult

find for help

this is the procedure

here are my Question

1. Work out why the delay between transmit and receive data is 16.
2. In Module 4, there are no errors detected when the error calculation block was implemented. What is the reason for errors occurring in Module 5?
3. How does the Eb/No setting in AWGN block affects the BER of the system in Module 5?
4. In the Error Rate Calculation block, explain the function of the Stop Simulation Criterion, Target number of errors, and Maximum number of symbols.
5. In Module 5, as extra exercise, you were asked to implement an 8 PSK system. What are the changes that need to be made to the QPSK system in order to implement a 8PSK system? Details which block and parameters were changed. Give explanation for each of the changes made.
6. In reference to the 8 PSK system that you have simulated under the same BER vs SNR performance criteria for Module 5, comment on the performance of the 8PSK system compared to the QPSK system. Which modulation system performs better? Explain.

These are questions based around communications theory, and not really based on Simulink. You should be studying them in communications theory resources.
