Teletext reception in a mobile channel for a broadcast tele-information system

A system is proposed for informing passengers who travel by train during their journey. An important part of the system is mobile communication. Teletext is chosen as an information medium, and the possibility of mobile teletext reception is analyzed considering selection diversity (SD) and maximal ratio combining (MRC). The bit error probability is calculated by modeling the channel as a shadowed-Rician fading channel. Picture quality is measured with average number of errors per page (ANEP). Thus performance is measured in terms of bit error probability (BER) and average number of errors per page. Finally, the level crossing rate, average fade, and average nonfade durations are also evaluated.<
