Signal-cancellation Based blocker Jamming

A signal processing circuit and method suitable for eliminating co-channel interference in digital signals uses adaptive filters to estimate co-channel Jamming signal in received digital signals. The adaptive filter takes the received digital signal minus the code information output by the decider as input, so the output of the adaptive filter does not include code information.

A circuit and method for eliminating co-channel interference, using signals from which code information has been subtracted as an input to an adaptive filter to predict co-channel interference to eliminate co-channel interference in digital data, and avoid generating additional inter-symbol interference.The composite video signal is processed at the transmission end to remove line synchronization code and frame synchronization code and replace it with frequency hopping synchronization code.
