Signal Design for Improved Reliability
It was recognized very early during the development of communications that the possible transmission rate of symbols of a communication channel depended on its frequency response of attenuation and phase shift. For instance, the famous theorem by NYQUIST  and KÜPFMÜLLER [2,3] state s that one independent symbol may be transmitted per time interval of duration τ through an idealized frequency lowpass filter of bandwidth Δf, where
$$ \tau = 1/2\Delta f $$
