Abstract :
Channel precoding for an ISI channel is discussed in this paper with emphasis on the complexity of the equalizer. An FIR filterbank based precoder with a simple decoder utilizing nonuniform sampling is derived. Such a precoder is then generalized to an equalizer constructed from nonconsecutive samples. The latter system is shown to be more computationally efficient. Design examples are presented to demonstrate the derived channel precoders
