碩士 === 國立交通大學 === 電子研究所 === 83 === Offtract or intertrack interference (ITI) is the result of recording head position error and is often the dominant noise source in multi-track channel such as magnetic-disk storage or digital compact cassette (DCC). Therefore, equalizers which are able to combat both ISI and ITI must be considered. In this thesis, we present a pseudo two-dimentional LMS adaptive equalizer suitable for multiple-input-multiple-output (MIMO) parallel requirement, with reduced complexity comparing with a 2-D equalizer structure. Simulation result shows that the performance of this equalizer is comparable to that of the 2-D equalizer.
