Question

Using the signal constellation shown, answer the following questions. (a) What type of modulation does this represent? (b) How many symbols are represented (M)? (c) How many bits per symbol are used (L)? (d) If the Baud is 10,000 symbols/second, what is the bit rate (R)? (e) Would 16-QAM be more or less susceptible to noise than this type of modulation?

Step 1

(b) To determine the number of symbols (M), we need to count the distinct points in the constellation diagram. Assuming it's a standard PSK constellation, there are likely 8 distinct points, so M = 8. (c) Show more…
