摘要： In this paper, a time-domain adaptive decision feedback equaliser (ADFE) for multi-gigabit wire-line 2-pulse amplitude modulation (PAM) communication systems is proposed. The throughput rate of a conventional ADFE is limited by the loops in the circuit. This investigation develops two methods for breaking or virtually breaking these loops. The first is the method of batch mode coefficient updating (BMCU), and the second is the concurrent look-ahead (CLA) method. Since the loops are broken or virtually broken, a pipeline and/or a parallel method can be applied to design a throughput-rate-unlimited ADFE. The results of a simulation of the 10GBASE-S system reveal that the proposed BMCU-based CLA ADFE has the same average signal-to-noise ratio as the original sequential ADFE for multi-mode fibres of length 30-90 m. 出版者： Stevenage: Institution of Engineering and Technology 出版日期： 2012-01-01 出處： IET circuits, devices & systems, 2012-01, Vol.6 (1), p.52-62 版權： 2015 INIST-CNRS 版權： Copyright The Institution of Engineering & Technology Jan 2012 識別號： ISSN: 1751-858X 識別號： EISSN: 1751-8598 識別號： DOI: 10.1049/iet-cds.2010.0445
