COMMUNICATION IN A SWITCHING NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18399672 titled 'COMMUNICATION IN A SWITCHING NETWORK

Simplified Explanation: The patent application describes a switching network that enables point-to-point communication between nodes by activating and deactivating multiple channels. During a training phase, known signals are transmitted to determine equalizer coefficients for each channel, which are then stored for use in scheduled communications.

Original Abstract Submitted

A switching network for effecting point-to-point communication between nodes has a time-varying switching configuration, which causes successive activation and deactivation of multiple channels of the switching network, a first of the channels connecting, when activated, a transmitter node and a first receiver node, and a second of the channels connecting, when activated, the transmitter node and a second receiver node. In a training phase, a method comprises: transmitting from the transmitter node via each channel a known training signal, to cause each receiver node to receive a distorted training signal, using the first distorted training signal and knowledge of the first known training signal to determine respective one or more transmit-side equalizer (EQ) coefficients for each channel, and storing, in memory accessible to the transmitter node, the first transmit-side EQ coefficients, in association with each channel, for use in conducting scheduled communications over the switching network in a communications phase.
