Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
 
Description Forward error correction and coded modulation are considered for the digital subscriber line. In particular, the user error rate performance of the legacy concatenated Reed Solomon and Trellis Coded Modulation system is compared to that achieved by the binary and non-binary Low-density Parity-check Bit-interleaved Coded Modulation system. The comparisons are made for the system with linear precoding cancellation of far-end crosstalk. Significant improvements are achieved by the modern capacity-approaching codes. The results have been submitted to ITU and are considered for inclusion in the next standard.
Exploitation Route We have been working closely with the project partners of the Celtic Plus project and British Telecommunications (BT) to replace the legacy error correcting codes (ECC) utilized in the standard by state-of-the-art ECC techniques.
