The design and performance of high-bit-rate digital subscriber loop (HDSL) transceivers is examined with the intention of devising systems with signal processing and technology requirements that are not vastly dissimilar to those of basic access transceivers. The topology, line codes, postcursor equalization, precursor equalization, and noise prediction of a simple HDSL transceiver are discussed. A design strategy that would allow early development of an HDSL transceiver to provide 800-kb/s access is explored. A useful benchmark against which the performance versus complexity tradeoff of more sophisticated systems may be assessed is described. >read more

New automatic equaliser employing modulo arithmetic
TL;DR: In this paper, it is shown that modulo arithmetic may be used in the inverse filter to eliminate completely the possibility of instability, and a very simple automatic or adaptive equalisation system is presented.

Detection of coded modulation signals on linear, severely distorted channels using decision-feedback noise prediction with interleaving
TL;DR: A technique is proposed that combines periodic interleaving with noise-predictive DFE, so that delayed reliable decisions can be used for feedback, and can attain the DFE performance on severely distorted channels.

The feasibility of using adaptive transmitters to suppress crosstalk
TL;DR: It is shown that using optimized block codes of insufficient length results in unstable adaptation of the transceivers and concomitant severe transmission distortion, but if the code blocks are greater than a certain critical length determined by, among other things, the number of pairs involved, near-end crosstalk can be completely eliminated.
