Issue of IEEE 802.20 vehicular-A delay profile model on estimating received signal level variation of wideband signal

This paper estimates a received signal level variation in a mobile broadband wireless access system using the Institute of Electrical and Electronics Engineers (IEEE) 802.20 vehicular-A delay profile model through a computer simulation. The simulation results show that wider signal bandwidth yields a narrower variation range of the received signal level when the bandwidth is narrower than 3 MHz. When the signal bandwidth is wider than 3 MHz, the variation range of the received signal level is not decreased with an increase of the bandwidth since the channel transfer function is quasi-periodical. We consider that the IEEE 802.20 vehicular-A delay profile model is appropriate to calculate the received signal level variation when the signal bandwidth is narrower than 3 MHz.
