IMPACT OF SHAPES OF BUILDINGS AND METALLIC FURNITURE ON INDOOR MULTIPATH ENVIRONMENT AND BIT-ERROR RATE PERFORMANCE OF MILLIMETER-WAVE CHANNEL

Wideband communication characteristics of millimeter-wave channels for rectangular and arched buildings with and without metallic furniture are investigated. The impulse responses of rectangular and arched buil dings for any transmitter-receiver location are computed by shooting a nd bouncing ray/image techniques. By using the impulse responses of th ese multipath channels, the impact of the shapes of building and metal lic furniture on an indoor multipath environment is investigated. In a ddition, the outage probabilities for a BPSK (binary phase-shift keyin g) system with phase and timing recovery circuits are calculated. Nume rical results show that the mean rms delay spread for arched buildings is smaller than that for rectangular buildings. Moreover, it is also found that when the receiver is located near metallic furniture, the m ultipath effect caused by the metallic furniture is severe. In additio n, numerical results also show that the outage probability for an arch ed building is lower than that for a rectangular building. (C) 1998 Jo hn Wiley & Sons, Inc.
