###### Question details

Digital Communications class

- We know the BER of a BPSK system in AWGN channel is
Q(sqrt(2E
_{0}/N_{o})) What is the BER of a 2ASK system? A digital 3ASK modulation output waveform as;

s_{0}(t)= -A cos(2 pi
f_{c} t), 0 < t <= T

s_{1}(t)= 0, 0 < t <=
T

s_{2}(t)= A cos(2 pi
f_{c} t), 0 < t <= T

What is the SER of this 3ASK system in AWGN channel?
