Multimode signaling on non-ideal channels

Simultaneous optimization of interconnect density and crosstalk poses conflicting requirements with conventional differential signaling. As an alternative, we investigate multimode signaling where n signals are transmitted by exciting all fundamental modes on a group of n closely located lines. In this paper, the channel response of multimode signaling is analyzed to demonstrate the benefits of this signaling. The misaligned channel and length mismatch sensitivity of multimode signaling are also analyzed.
