Efficient real data filtering using complex-input discrete Fourier transforms
چکیده انگلیسی

A new algorithm for efficient linear convolution of real signals using discrete Fourier transforms is presented. The traditional method uses a considerable amount of pre-processing and post-processing of both the input and output signals. We show that plenty of this processing can be shifted to the impulse response of the system, whose operations can be precomputed and therefore have no computational cost. This method results in computational savings, reducing the total arithmetic operations and particularly the execution time with regard to previously proposed techniques.
