Abstract

A multiplexer receives a message from a first bus and a message from a second bus, wherein a preamble is received at the head of each message, compares the preamble from each bus against an ideal preamble and, prior to receiving the next bit in either message, provides to a transceiver the message which is least noisy as indicated by the comparison; if the preamble in the message on the bus presently selected for reception by the transceiver does not compare favorably with the ideal preamble, the message from the other bus is selected.
