摘要： A novel method and apparatus is disclosed, that embeds with, or otherwise makes available to an adaptive equalizer, suitable for use in IEEE 1OG-LRM standard compliant receivers, digital logic that monitors some of the Layer 1 and preferably some of the Layer 2 processing that typically occurs after the equalization step during decoding and processing of the record data stream. From this additional logic information, the equalizer is able to make a much more accurate prediction of equalizer convergence by counting processing errors and prove convergence by calculation of BER. The novel method and apparatus are applicable to ASIC embodiments and the complexity of the logic information obtained can be programmably scaled back or enhanced as appropriate in light of the particular communication environment.

摘要： A novel method and apparatus is disclosed, that embeds with, or otherwise makes available to an adaptive equalizer, suitable for use in IEEE 10G-LRM standard compliant receivers, digital logic that monitors some of the Layer 1 and preferably some of the Layer 2 processing that typically occurs after the equalization step during decoding and processing of the record data stream. From this additional logic information, the equalizer is able to make a much more accurate prediction of equalizer convergence by counting processing errors and prove convergence by calculation of BER. The novel method and apparatus are applicable to ASIC embodiments and the complexity of the logic information obtained can be programmably scaled back or enhanced as appropriate in light of the particular communication environment.
