Abstract :
The performance of an indoor wireless spread-spectrum communication system is conveniently analyzed assuming that the multipath profile is a constant function of delay. However, experimental measurements appear to fit an exponential profile better. Assuming flat Rayleigh fading and an exponential multipath profile, we derive a closed form expression for the bit error rate of BPSK with spread-spectrum and antenna diversity. Comparison of these results with simulated results based on actual channel measurements shows that the exponential profile model differs from the simulation model by only 1-2 dB whereas the constant profile model differs by as much as 5 dB
