In recent years there has been considerable interest in digital transmission-through existing telephone lines. It is believed that transmission at rates up to 1 Mbps or higher can be facilitated. In this thesis the problem of Equalization of twisted-pair cables with bridged taps is studied. The minimum MSE is calculated in the presence of Near-end Cross-talk and white Gaussian noise, at two data rates 80 Kbs/640 Kbs and for four coding schemes (Binary;, Duobinary, Bipolar, Manchester) supported by infinite Linear^and Decision-feedback Equalizers. The performance of a novel simple decision-feedback receiver with Automatic line Build-out CALBO) is also investigated. It is shown that this easy-to-implement structure is a fairly robust one as it performs better than the infinite Linear Equalizer for high cross-talk interference.
