Question details

Question 1 -(25 pts) (a) (5 pts) A 3 kHz bandpass channel is to be used for transmission of M-QAM modulated symbols at a rate of Rb 9600 bits/sec. 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. What is the value of r? Plot the constellation diagram of the above 16-0AM modulation scheme. 10-6. at a rate of now Rb 16000 bits/sec. (b) (7 pts) Determine the E,/No at the receiver (in dB) that achieves a bit error probability of (c) (8 pts) A 3 kHz bandpass channel is to be used for transmission of M-QAM modulated symbols (4 pts) What is the minimum value of M suitable for this transmission? (4 pts) Determine the E,/No at the receiver (in dB) that achieves a bit error probability of 10-6 a. b. (d) (5 pts) Create a table and compare your results found in part (c) and part (d). Do your results make sense?
