Multi-line Coordinated Communication

The interest in designing high-speed communicationsystems over metallic wire conductors remains verystrong. This interest is exemplified by efforts todeliver Very-high-speed Digital SubscriberLine (VDSL) systems Ethernet-in-the-First-Mile(EFM) multi-Gbps Ethernet over copper twisted pairsof short length and multi-Gbps chip-to-chip seriallinks over cable or backplane traces. A prevailingcharacteristic of such systems is that multiple linesemanate from a central node and reach remoteterminals. Crosstalk amongthe lines is in several cases the dominantconstraining factor for communication. This work examines how coordination among signals ofdifferent lines during transmission or receptionfacilitates reliable high-speed communication. Afundamental result of this work is that suchcoordination inmulti-line channels is capable of achievingperformance that is very close to that attained inthe absence of crosstalk.
