Artículo de publicación ISIDigital communication systems are characterized by having a filter at the
transmitter and receiver sides to band limit the transmitted signals and diminish the effects
to intersymbol interference (ISI). The optimum parametric linear combination pulse is
evaluated at the transmitter and receiver sides by using different evaluation tools. The
proposed pulse is evaluated in terms of the bit error rate in the presence of symbol-timing
errors. Eye diagrams are presented to visually evaluate the susceptibility of the transmission
system to ISI, and the maximum distortion is determined as a numerical measure
of performance.Program U-INICIA VID, University of Chile
