Abstract
An interference cancellation system and method for a communication system comprising a data bus carrying primary signals having an A component and a non-A component are provided. The interference cancellation system has an input port, an A data extraction block and an interference cancellation circuit. The input port receives a sampled primary signal from the data bus, via an analog-front end block having sampling means. The A data extraction block extracts A data from the sampled primary signal and outputs A decoded data. The interference cancellation circuit has an interference measurement block and a cancellation block. The interference measurement block receives the A decoded data and the sampled primary signal and produces an A interference signal. The cancellation block receives the sampled primary signal and the A interference signal and subtracts the A interference signal from the sampled primary signal, producing an output signal with the A component substantially attenuated.
