Abstract

Summary form only given. A new maximum likelihood sequence detection (MLSD) technique to reduce the effects of inter-track interference (ITI) is presented in this paper. As track densities increase, ITI and off-track interference (OTI) occur, and have detrimental effects on the performance of current MLSD decoders. A solution is to perform MLSD with an adaptive ITI equaliser constructed within the decoder trellis.
