Question 2-(35 pts) (a) (10 pts) A 3 kHz bandpass channel is to be used for transmission of M-QAM modulated symbols at a rate of R₂ = 9600 bits/sec. (4 pts) Show that the minimum value of M suitable for this transmission is M =16. Use a Nyquist Criterion pulse with a suitable roll off factor, r. (3 pts) What is the value of r? (3 pts) Plot the constellation diagram of the above 16-QAM modulation scheme. (b) (5 pts) Determine the E/No at the receiver (in dB) that achieves a bit error probability of 10-6. (c) (5 pts) What should be the E/No if 16-PAM were used instead of 16-QAM in part (b)? (d) (10 pts) A 3 kHz bandpass channel is to be used for transmission of M-QAM modulated symbols at a rate of now R, = 16000 bits/sec. (5 pts) What is the minimum value of M suitable for this transmission? (5 pts) Determine the Eb/No at the receiver (in dB) that achieves a bit error probability of 10-6. (e) (5 pts) Create a table and compare your results found in parts (a), (b) and (c), (d).
