Effects of Filtering Allocation on the Performance of a Modified Duobinary System
E.A. Newcombe, S. Pasupathy · IRE Transactions on Communications Systems · 1980
The effects of changing the allocation of filtering on the performance of a modified duobinary partial response system are examined. Two classes of filtering as well as two types of decoders are considered. The precoded system is, in general, superior to the system with decision feedback decoding, except at low values of the signal-to-noise-ratio and large fractions of the filtering at the receiver.
