Abstract

Single-Pair High-Speed Digital Subscriber Line (SHDSL) technology allows for symmetric data transmission at rates up to 2.312 Mbps over one twisted-wire-pair. In comparison, HDSL, which has been in service since 1992, uses two pairs to transmit data at the rate of 1.544 or 2.048 Mbps. SHDSL uses trellis coded modulation and Viterbi decoding in order to achieve target data rates. This talk will cover the fundamentals of SHDSL transceivers and will focus on the design and implementation the transceiver's digital subsystems.

Biography

Kelly K. Johnson received a Ph.D. degree in Electrical Engineering from the University of Texas at Austin in 1997, her graduate work focused on discrete-time nonlinear digital systems. During the last four years she has worked in the semiconductor industry on the development of DSL transceivers and broadband networking devices. She is currently an adjunct faculty member in the Department of Electrical and Computer Engineering at the University of Texas at Austin.
