The electronic system occasionally requires the simultaneous transmission and reception of signals in the same platform. In the circumstance of simultaneous transmission and reception, the strong coupling interference signal cancellation requires shorter data and better cancellation effectiveness, but the cancellation performance of general causal canceller is relatively poor. Motivated by this, adopting non-causal filter to realize digital cancellation is then proposed in the paper. The model of non-causal filter digital cancellation is built at first, and the digital cancellation is simulated and analysed. The simulation results demonstrate that the digital cancellation has outstanding characteristics, and at the same time, the results also indicate that in the circumstance of the same filter order, the non-causal filter digital cancellation has better cancellation effectiveness.
