An embedded pattern-based adaptive equalizer coefficient updating mechanism updates weighting coefficients of an adaptive equalizer in accordance with an error or differential signal obtained by processing the distorted version of a known signal pattern, that is repetitively distributed among information signals contained within the electrical communication signal output from the equalizer, with a copy of the known signal pattern. No dedicated 'training sequence' communication with the transmitter is required, so that the coefficient update mechanism does not impact the operation or bandwidth availability of the channel.

Updating adaptive equalizer coefficients using known or predictable bit patterns distributed among unknown data

An apparatus for communicating information over a pressurized fluid-carrying pipe connecting a plurality of serial nodes. A sounder node (i.e., transmitter) creates variable pressure patterns within the fluid-carrying pipe, which pressure patterns are identified and detected by other nodes. The patterns convey information or solicit responses from the receiving nodes. The receiving nodes reply to the pressure fluctuations by inducing reply pressure fluctuations in the fluid-carrying pipe or by communicating with the sounder node via a separate radio frequency communications system. The apparatus and method can be used as an information-carrying communications medium or a train linking methodology for a railroad train.
