Abstract:
CDMA2000 1X capacity was analysed in the high speed train environment. We calculated the power control error by Doppler shift and simulated bit error rate (BER) at the base station. We made the interference model and calculated the BER from lower bound of power control error variance. The reverse link BER was increased by high velocity although there was no coverage reduction. Capacity decrease was negligible in the pedestrian (5 km/h), urban vehicular(40 km/h), highway and railroad(100 km/h) environment. However, capacity was severely reduced in high speed train condition(300 km/h and 350 km/h). Cell-planning considering capacity as well as coverage is essential for successful cellular service in high speed train.
