Shooting and bouncing ray/image techniques are applied to compute theimpulse response for the double-deck subway station. By using theimpulse responses of these multipath channels, the bit error rateperformance of BPSK (binary phase shift keying) with OFDM (orthogonalfrequency division multiplexing) system are calculated. Numericalresults have shown that the multipath effect by the trains for thedouble-deck subway station is an important factor. In addition, theeffect of space diversity techniques on mitigating the multipathfading is also investigated. Finally, it is with noting that in thesecases the present work provides not only comparative information butalso quantitative information on the performance reduction.
