Abstract：RF interference cancellation is the good choice of radios inter-interference suppression in the same communication-command vehicle. However, the performance of cancellation is limited to the actual devices. Given this problem, the impact of key attenuator error on RF interference cancellation system is analyzed in theory. Firstly, the interference cancellation system based on adaptive orthogonal feedback control is built. Then the theoretical analysis of how the attenuator response-time and accuracy error reduce performance of interference system is shown, and the closed expressions between attenuator response-time and system convergence-time, attenuator error and cancellation ratio are derived respectively. Finally, the simulations verify the validity of closed expressions, which is significant for practical
application.
