Abstract :
Circular polarization diversity with passive reflectors is investigated in an indoor radio channel, and its performance is evaluated with a three-dimensional (3-D) ray-tracing simulation in conjunction with a geometric-optics-based facet approximation. The simulation results show that the use of passive reflectors improves the outage probability of an indoor radio channel for base stations which exploit circular polarization diversity and the diversity gain increases with the reflector size
