Abstract
Digital video broadcasting through satellite transmission will provide new services to aeronautical, railway and maritime mobile terminals. However, mobile channel impairments request effective countermeasures to improve the C/N performance and counteract Doppler spread. The paper investigates the application of MPE-FEC (multi protocol encapsulation -forward error correction) to DVB-S2 standard chain for railway applications. In this scenario, trellis power arches may introduce deep fading events which cause bursts of data losses. An analytical model describing MPE-FEC decoder performance has been derived and validated through numerical simulation considering different train speed values, MOD-COD (modulation order and physical layer coding rate) configurations and number of rows in the MPE-FEC frame. Results show that, depending on the train speed, enlarging the number of rows or adopting a sliding encoding mechanism are effective in counteracting power arches impairments.
