Impact of shapes of buildings and metallic furniture on indoor multipath environment and bit-error rate performance of millimeter-wave channel

Abstract

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 buildings for any transmitter–receiver location are computed by shooting and bouncing ray/image techniques. By using the impulse responses of these multipath channels, the impact of the shapes of building and metallic furniture on an indoor multipath environment is investigated. In addition, the outage probabilities for a BPSK (binary phase-shift keying) system with phase and timing recovery circuits are calculated. Numerical 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 multipath effect caused by the metallic furniture is severe. In addition, numerical results also show that the outage probability for an arched building is lower than that for a rectangular building. © 1998 John Wiley & Sons, Inc.
