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 ( N 2 ) to O ( N log 2 N ). 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. © 2003 Wiley Periodicals, Inc.
