Bit-error rate performance of indoor millimeter-wave channel for gymnasiums

Wideband communication characteristics for two different geometrical configurations of a gymnasium at 57.5 GHz are investigated. Shooting and bouncing ray/image techniques are applied to compute the impulse response By using the impulse response of these multipath channels, the outage probability for high-speed BPSK (binary phase-shift keying) systems with phase and timing recovery circuits is calculated. Numerical results show that the mean delay spread for the dome-shaped gymnasium is smaller than that for the square-shaped gymnasium. Moreover; the mean delay spread for the region near the center of the gymnasiums is larger than that for the region far away from the center. In addition, if is also found that communication is not feasible even if the transmission rate is as low as 2.5 Mbits/s. (C) 1998 John Wiley & Sons, Inc.
