with pulse shaping filter
pt=Ke-t2ut, where
ut is the unit
step function. The transmitted waveform is a0p(t), and
symbol a0 belongs to a 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 value of K such that the
pulse has unit energy?
