In this article, we introduce a novel group of space-time-frequency codes based on multiple trellis coded modulation (MTCM). These codes are originally designed without accounting for the channel spectral and temporal correlation conditions. We improve the code performance by utilizing an augmented distance spectrum enhancement technique to serve for the wireless channels that undergo mobility and multi path fading. The performance of the new group of codes, with enhanced distance spectrum characteristics is investigated though numerical simulations
