shaping filter
pt=e-t2ut, where
ut is the unit
step function. The transmitted waveform is a0p(t), and
symbol a0 belongs to an ASK constellation with
intersymbol spacing d. The noise at the receiver is additive white
Gaussian with autocorrelation
N02δt . At the receiver,
the signal is passed through the optimal filter followed by
sampling at T. What is the resulting probability of error?
