Abstract

This paper presents a new mathematical analysis for the performance of orthogonal frequency-division multiplexed (OFDM) signals over multipath Nakagami-m fading channels. In contrast to the previous research, this paper focuses on the effects of the nonuniform phase distribution on the error rate performance. A unified expression is derived for the moment generating function (MGF) of the frequency-domain channel gains on Nakagami-m channels with nonuniform phase distributions. Classical MGF methods can then be straightforwardly employed to obtain accurate error rates expressions for different modulation and diversity formats.
