摘要: 磁頭位置偏差所造成的軌際干擾(ITI)在多軌通道系統中(例如磁碟機或數 位式緊密卡帶(DCC)往往是最主要的雜訊。 因此,等化器的設計必須同時 考慮到能處理符際干擾(ISI)和軌際干擾(ITI)。在論文中,我們提出了一 個擬二維最小均方(LMS)的適應性等化器。 因為它的電路複雜度較標準的 二維等化器來得簡單,所以特別適合於平行多輸入多輸出(MOMO)的使用。 從模擬的結果可看出,這個擬似二維等化器與二維等化器有一樣的表現。 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.
