A feedback filter, fed by the detector, is subtracted from a feedforward filter, fed the input signal, to reduce the incidence of this phenomenon in the decision-feedback equalizer. In the presence of 3 this phenomenon, the optimal detector is the maximum-likelihood sequence detector, though it's unwieldy at increasing sequence lengths. This phenomenon decreases the noise margin and increases the sensitivity to timing error because it distorts the zero crossings on an eye pattern, causing the eye 6 to narrow. This phenomenon is eliminated if the Fourier transform of a transmitted signal satisfies therelation X of f plus m divided by the sampling period equals the sampling period for −∞ &lt; m &lt; +∞;that relation satisfies the Nyquist criterion for having zero of this phenomenon. The incidence of 9 this phenomenon is commonly reduced by eschewing square pulses for pulses with a (*) raised cosine spectrum. For 10 points, name this phenomenon in which subsequent symbols are distorted by the Dopplerspreading and "smearing" of previously transmitted symbols.
