Patent ID: 7822126

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, wherein the 1553 decoded data further comprises a 1553 word timing estimate; and an interference cancellation circuit comprising: an interference measurement block for receiving said 1553 decoded data and said sampled primary signal and for producing an interference signal the interference measurement block comprising an accumulate basis function block, for receiving said 1553 decoded bit stream, said 1553 word timing and said sampled primary signal and for extracting 1553 basis function representations in a non-1553 frequency band; and a cancellation block for subtracting the interference signal from the sampled primary signal and for producing an output signal.
