Title:
TRAINING-BASED BACKPLANE CROSSTALK CANCELLATION
Document Type and Number:
WIPO Patent Application WO/2018/113670
Kind Code:
A1
Abstract:
A system, computer readable medium, and method are provided for training a serial communication link to perform crosstalk cancellation. The method includes the steps of, for each crosstalk channel of one or more crosstalk channels, transmitting a training sequence over a crosstalk channel, estimating a phase offset associated with the crosstalk channel, and selecting a set of symbol response coefficients. The method further includes steps for configuring the serial communication link to perform crosstalk cancellation utilizing the selected set of symbol response coefficients and, for each crosstalk channel, updating the selected set of symbol response coefficients every number of Baud durations corresponding to the crosstalk channel.
