dc.description.abstractThe main objective of this work is to study echo cancellation and equalization for primary rate ISDN service in the subscriber loop plant. Such a system will enable T1-rate services over the subscriber loop by using transceivers at either end of the telephone connection. Echo cancellation and equalization are two important functions needed in the trans­ceiver for achieving the high communication rate over unconditioned subscriber lines. These functions use adaptive filtering concepts and form the main focus of our research. Duplex communication over the subscriber loop plant is achieved by using echo can­cellation. We use simulation models to demonstrate a successful echo canceler for worst­ case conditions. The echo canceler satisfies preset performance conditions. Some tech­niques for reducing the length of the echo canceler are also presented along with successful simulation results. Equalization is primarily used for eliminating interference from different signals in the same multipair cable. A recently developed theory is used to achieve a successful equal­ization strategy for this primary rate service. A simulation environment built for the equal­izer is detailed and satisfactory equalizer performance is shown to be achieved using exten­sive simulation results.en
