Impact of Shadowing Correlation on Spectrum Efficiency of a Power Controlled Cellular System
Kentarou Sawa, Eisuke Kudoh, Fumiyuki Adachi · 2004
Abstract: Independent shadowing losses are often assumed for computing the frequency reuse distance of cellular mobile communication systems. However, shadowing losses may be partially correlated since the obstacles surrounding a mobile station block similarly the desired signal and interfering signals. We investigate, by computer simulation, how the shadowing correlation impacts the frequency reuse distance of a power controlled cellular system. It is pointed out that the shadowing correlation impacts the frequency reuse distance differently for the uplink and downlink. key words: Cellular system, frequency reuse distance, transmit power control, outage, shadowing correlation 1.
