Estimation of multipath fading outage in short-haul network based on a statistical model

A statistical model to evaluate the feasibility of installing high-capacity digital radios in the 6-GHz short-haul microwave network is presented. Improvement in network performance due to installation of high-capacity radios can be determined by estimating the number of acceptable hops that meet system requirements for multipath fading outage. Cases with and without interference are examined. The results show that with enough protection, such as frequency diversity and space diversity at the appropriate places, the 64-QAM (quadrature amplitude modulation) digital radio system will meet the multipath fading outage requirements on virtually all hops for a 6-GHz short-haul network.>
