Abstract

The bit error rate (BER) performance for high-speed personal communication service in tunnels with and without traffic is investigated. The impulse responses of tunnels for any transmitter--receiver location are computed by shooting and bouncing ray/image techniques. By using the impulse responses of these multipath channels, the BER performance of BPSK (binary phase shift keying) system with phase and timing recovery circuits are calculated. Numerical results have shown that the multipath effect by the vehicles in the tunnel is an important factor for BER performance. In addition, the effect of space diversity techniques and decision feedback equalizer on mitigating the multipath fading is also investigated.
