Question
Let an inter symbol interference free system is operating with 2* PSK symbols over a channel
with a bandwidth of 120 kHz and the required minimum bit rate is 900 kbps.
a. Find the minimum signal to noise ratio (SNR) to receive the symbols without a
probability of bit error 10-6 or less?
b. Repeat part (a) for an M-ary QAM system and calculate the new minimum SNR with
a probability of bit error of 10 or less?
c. Make comparison between part (a) and part (b) and comment on the results.
