Abstract
Vector signaling code communications systems rely on group transmission of code symbols using multiple signaling channels that may have differing propagation characteristics, resulting in differing received signal levels, waveforms, and symbol arrival times, and thus that should be actively monitored and adjusted to minimize differential signal characteristics. Information obtained during symbol decode may be analyzed to identify channel operational characteristics during normal operation and perform non-disruptive channel adjustments, including per-channel adjustment of sample-and-hold timing to realign code symbol groups. Initialization or start-up adjustment may also be performed using intentionally-transmitted training patterns.
