Abstract :
It is shown that in direct line-of-sight communications multiple reflections which give rise to Rician amplitude fading statistics need not degrade performance (compared to the case of specular component only), provided the fading is slow compared to several bit times and sufficient interleaving with powerful low rate coding is employed. Theoretical bounds as well as simulation results with practical codes are presented to support this conclusion.
