A Study of the Permutation Schemes Used in the Mobile WIMAX

Abstract

With the goal of decreasing the interference at sub-carrier level, the allocation of sub-carrier frequencies in an OFDMA based system is selective. This selective allocation can be seen like a permutation of a frequency “sequence”. This paper proposes a new analyzing tool for the frequencies permutation used in WiMAX mobile communications: the distances spectrum (DS). This tool can offer a meaningful measure for these permutations, with respect to the most performing permutations used in turbo-codes, which, given their major importance, are strongly studied and developed.
