Outage probability comparison of distributed antenna diversity and single site antenna diversity

In highly built-up urban areas, where shadowing is a severe problem, distributed antenna diversity represents a more effective fade mitigation scheme than conventional single site antenna diversity. It integrates the advantage of both micro and macro antenna diversities. In this contribution, a hybrid model using Gaussian fast fading and ray tracing is used to obtain the unconditional outage probability and the performance of the distributed antenna and single site antenna structures are compared. For the distributed antenna a comparison between coherent combining diversity and selection diversity schemes has also been made.
