Patent ID: 7907690

Claim:
Within a 1553 communication system comprising a data bus carrying primary signals having a 1553 component and a non-1553 component, an interference cancellation system comprising: an input port for receiving a sampled primary signal from the data bus, via an analog-front end block comprising sampling means; a 1553 data extraction block connected to said input port, for extracting 1553 data from said sampled primary signal and for outputting 1553 decoded data; and an interference cancellation circuit comprising: an interference measurement block for receiving said 1553 decoded data and said sampled primary signal, said interference measurement block comprising an impulse response block for producing an interference signal based on a 1553 impulse response system model and a generate reference block for producing a reference signal based on said 1553 decoded data and based on predetermined impulse sequences and wherein said impulse response block receives said reference signal; and a cancellation block for subtracting the interference signal from the sampled primary signal and for producing an output signal with the 1553.
