Abstract :
This paper presents an anti-multipath fading scheme employing a circular polarization wave for line-of-sight (LOS) indoor radio communications. The circular polarization wave transmission significantly mitigates the multipath fading caused by reflections from walls, ceiling, and floor since the energies of single-bounce reflected waves do not appear at the receiver, thereby resulting in significant amplitude fade and delay spread reduction. The received signal intensity variations and delay spread are investigated numerically using a 14-path propagation model
