Data communications system and method of data transmission
First Claim
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.

Abstract
A 1553 data communication system having a primary data bus, a redundant data bus and a non-1553 data communication overlay system is provided. The non-1553 data communication overlay system comprises a non-1553 bus controller terminal and a non-1553 remote terminal. Each non-1553 terminal includes a non-1553 transmitter block connected to the primary bus and the redundant bus for sending non-1553 signals, a non-1553 receiver block for receiving non-1553 signals and a non-1553 receive path selection block. The non-1553 receive path selection block selectively establishes a receive path between the primary data bus or the redundant data bus and the non-1553 receiver block according to predefined receive path selection criteria. A 1553 data communication method is also provided.

13. A 1553 data communication system comprising:
-
a primary data bus; a redundant data bus; a 1553 bus controller terminal and a plurality of 1553 remote terminals, each of the 1553 remote terminals comprising; a 1553 transmitter block; an analog switch, for selectively connecting the 1553 transmitter block either to the primary bus or to the redundant bus according to a predefined receive path selection criteria and according to bus fault design; a first 1553 receiver block for receiving 1553 signals from the primary bus, under no-bus fault conditions; and a second 1553 receiver block for receiving signals from the redundant bus under bus-fault conditions; an OFDM bus controller terminal and a plurality of OFDM remote terminals, each of the OFDM remote terminals comprising; an OFDM transmitter block connected to the primary bus and the redundant bus for sending OFDM signals on the primary bus and on the redundant bus;
wherein the OFDM signals are configurable within a range between 0 MHz and 80 MHz;an OFDM receiver block; and an OFDM receive path selection block for monitoring the performance of the primary bus and of the redundant bus and for establishing a receive path between the OFDM receiver block and either the primary bus or the redundant bus based on performance metrics. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
