Abstract

The interference cancellation can restrain the strong interference between high power transmitter and receiver. The main point is to make sure the time delay between interference signal and reference signal match. The paper researches on the influence of time delay to the interference cancellation system. When the interference signal is single frequency signal, the ICR is unrelated with the time delay. When the interference signal is wideband signal, the ICR is related with the time delay. The simulation analysis and experiment results explain that ICR decreases as time delay increases if the bandwidth of the interference signal is the same, and the ICR decreases as the bandwidth of the interference signal increases if the time delay is the same.
