Long term fading in direct sequence spread spectrumin microcellular environments
M.P. Fitton, Mark A Beach, Andrew Nix · Electronics Letters · 1998
The shadowing (or long term) statistics of a wireless system have a large impact on overall performance. The authors show experimentally that the inherent path diversity of a direct sequence spread spectrum system will reduce the effect of long-term envelope variation due to shadowing. This will result in a network with more homogeneous quality-of-service, reduce handovers, and improve capacity.
