Abstract :
Effects of multipath propagation on a digital radio hop employing a plane reflector as a passive repeater were analysed by using a ray tracing method. The calculations of raypath parameters on the hop show that a large-aperture plane reflector increases attenuation fading due to the main ray´s angle-of-arrival variation by its sharp radiation pattern, and it can reduce dispersive fading. A digital transmission experiment on a reflector-equipped hop showed that plane reflectors could be used for small-capacity digital microwave systems.<>
