Data communications system and method of data transmission

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.

1 . Within a 1553 data communication system having a primary data bus and a redundant data bus, an non-1553 data communication overlay system comprising:
 an OFDM bus controller terminal and an OFDM remote terminal, wherein each OFDM terminal includes:
 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. 
   
     
     
         2 . A 1553 data communication system having a primary data bus and a redundant data bus and a non-1553 data communication overlay system, the non-1553 data communication overlay system comprising:
 a non-1553 bus controller terminal and a non-1553 remote terminal, wherein 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 for selectively establishing 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. 
   
     
     
         3 - 5 . (canceled) 
     
     
         6 . The non-1553 data communication overlay system of  claim 1 , wherein each non-1553 terminal comprises OFDM modems. 
     
     
         7 . The non-1553 data communication overlay system of  claim 1 , wherein said non-1553 signals are OFDM signals. 
     
     
         8 . (canceled) 
     
     
         9 . The non-1553 data communication overlay system of  claim 7 , wherein the OFDM signals are Power Spectral Density (PSD) configurable according to the topology of the 1553 data communication system.
