Multihop transmission is used in radio networks such as multihop cellular systems and mesh networks, and it may be superior to single-hop transmission under severe shadowing. In our previous studies, we modeled shadowing as a location-independent log-normal random variable and revealed the effect of multihop relaying on cellular communication systems. However, adjacent shadowing values are spatially correlated
because shadowing is caused by terrain configuration or obstacles between the transmitter and receiver. In this paper, we investigate the impact of decorrelation distance, whose typical value for the urban environment is 20 meters, on the coverage of multihop cellular systems in single-cell environments. By using a model for spatially correlated shadowing, numerical results reveal that when the coverage of single-hop cellular systems is ten times larger than the decorrelation distance, the introduction of multihop relaying may enhance the coverage without significant degradation due to the spatial correlation of shadowing. |
