The polarization effect on bit‐error‐rate performance for indoor wireless high‐speed communication is investigated. The transfer function of a single room is computed by shooting and bouncing ray techniques. By applying inverse Fourier transform to the frequency transfer function, the impulse response of the channel can be obtained. Binary data with phase‐shift keying modulation are transmitted over the multipath channel, and a coherent correlator is used as a receiver. The bit‐error rates for vertical, horizontal, and circular wave transmission/reception are calculated. Numerical results have showed the superiority of circular polarization over linear polarization for suppression of the multipath effects in indoor high‐speed transmission channel. The gain in signal‐to‐noise ratio for circular polarized waves compared with linear polarized waves under a given bit‐error rate is also computed. © 1996 John Wiley & Sons, Inc.
