In this work, a fast real-time convolution algorithm is proposed. By using this approach, the cost for real-time convolution in the presence of nonlinear terminations is reduced from O(N2) to O(Nlog2N). It is important to reduce the cost for the convolution operation because it usually dominates the computation time in a nonlinear circuit simulation. A nonlinearly-terminated microwave 3-port circuit, characterized by S parameters, is employed to demonstrate the efficiency of this fast algorithm.
