Outage and coverage considerations for microcellular mobile radio systems in a shadowed-Rician/shadowed-Nakagami environment

Abstract — This paper presents outage analysis and the as-sociated reuse distance and service area estimations for mi-crocellular mobile radio systems that operate in a shadowed-Rician/shadowed-Nakagami fading environment. Outages caused either by the minimum carrier-to-interference ratio (CIR) re-quirement alone or by the CIR plus the minimum signal strength [or, equivalently, carrier-to-noise ratio (CNR)] requirements are considered. The desired signal is assumed to suffer from Rician fading while the interference signals from cochannel cells expe-rience Nakagami fading. The interferers may have identical or different statistics. In addition, the local mean strength of the desired and interference signals may fluctuate due to shadowing. Index Terms—Coverage, microcellular, Nakagami, outage, Ri-cian. I
