1. Within a 1553 data communication system having a primary data bus and a redundant data bus, an OFDM data communication overlay system comprising:

  • an OFDM bus controller terminal and a plurality of OFDM remote terminals, wherein each of the OFDM remote terminals comprise;

    an OFDM transmitter block connected to the primary bus and the redundant bus for sending OFDM signals;

    an OFDM receiver block for receiving OFDM signals; and

    an OFDM receive path selection block for selectively establishing a receive path between the primary data bus or the redundant data bus and the OFDM receiver block according to predefined receive path selection criteria,wherein the OFDM signals are Power Spectral Density (PSD) configurable according to the topology of the 1553 data communication system and are configured to have a low PSD in a 1553b high energy frequency band and a flat high PSD in a 1553b low energy frequency band configurable within a range between 0 MHz and 80 MHz.
