Abstract

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.
