Abstract

In this paper, the structure of a trellis-coded 3-dimensional orthogonal frequency division multiplexing (3-D OFDM) is proposed and its error performance in additive white Gaussian channel is analyzed. We present the set-partitioning of a 3-D 8-ary constellation for trellis coding. As a result, the trellis-coded 3-D OFDM system has around 6 dB coding gain over an uncoded one when an 8-ary constellation is exploited. And it also has around 3 dB better symbol error probability as compared to the uncoded system when a 4-ary constellation is employed. Thus, the proposed trellis-coded 3-D OFDM may be appropriate for an application in the high-quality wireless communication system for the next generation.
