Abstract
A method of providing unequal error protection in a multi-carrier transmission, includes the steps of coding data for a multi-carrier-symbol duration by a coding process of a given minimum code distance, the given minimum code distance being a minimum of a distance between two codes that is measured in multidimensional code space with N sub-carriers; and changing the minimum code distance for each multi-carrier-symbol duration by changing the coding process.
