The effect of the sampling timing deviation on the minimum Euclidean distance and coding gains for the coded partial response signaling (PRS) channels is analyzed based on the vertical eye width of PRS by using the worst-data pattern. The authors compare the results with uncoded PRS channels as well as the corresponding coded two-level pulse amplitude modulation (PAM) in Nyquist raised-cosine channels. It is found that the reasonable total coding gains can be obtained when the sampling deviation is less than 10% of the bit interval for PRS channels. They also find that coded two-level PAM channels are less sensitive to the sampling deviation and obtain larger total coding gains than those for coded PRS channels.
