The structure of radix-2 Fast Fourier Transforms of length 2<sup>n</sup> where n is an integer is used to propose a new soft error detection and correction scheme for transform based convolution. The scheme can provide up to 100% detection and correction of isolated soft errors for, in many cases, approximately double the original system cost in terms of area and/or computational complexity. This is a substantial reduction when compared with conventional Triple Modular Redundancy. The method can be used for both hardware and software implementations of transform-based convolution.
