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