A Matlab code to simulate an OFDM with zero padding

—This paper shows a proposal for Type-reduction of an Interval Type-2 fuzzy set composed from α -cuts done over its primary membership functions. The defi nition of available Type-reduction methods for Interval Type-2 fuzzy sets are based on an homogeneous subdivision of the universe of discourse, so we propose an approximation algorithm for Type-reduction of an Interval type-2 fuzzy set through its primary α -cuts. Some defi nitions about the α -cut of a Type-2 fuzzy set are provided and used for computing the centroid of an Interval Type-2 fuzzy set through a mapping of its membership function, instead of its universe of discourse.
