Abstract

The error-pattern correction code is a code specialized to correct dominant error patterns observed at the channel detector output in heavy intersymbol interference channels. In this paper, we consider a turbo-equalizer system that utilizes the error-pattern correcting code (EPCC) as a building component. A soft-input soft-output (SISO) decoder for the EPCC is described, and the performance of the proposed turbo equalizer is compared with those of the conventional turbo equalizer and a low density parity check (LDPC) code system.
