EXAMPLE 7.2
Consider the two equally-likely signals s₁ (t) and s2(t) that are transmitted, over an AWGN channel
with the noise power spectral density of No/2, to represent bits 1 and 0, where we have:
S1(t)=-S2(t)=√√2 exp(-2t)u(t)
The receiver makes its decision solely based on observation of the received signal over a restricted
interval of interest. Determine the average bit error rate in terms of Q-function, assuming the
interval is [0,3]. Contrast numerically with the performance of an optimum receiver that observes.
