In this paper, outage probability caused by multiple interferers in Nakagami-m fading channels is studied. A novel method is proposed to derive the exact and closed form expressions of outage probability in the presence of multiple Nakagami independent cochannel interference. Unlike some previous conclusions, the method proposed in this paper is not only usable with various integer Nakagami fading parameters or average powers but also presents exact derivation of outage probability. To circumvent the difficulties, proper iteration functions are adopted by studying and integrating the definitions without numerical integration and residue calculation. The method generally deals with the cases that with or without minimum level constraint at the receiver for satisfactory reception. Finally, the exact expressions are compared with previous proposed approximated expressions and provide the understanding of the nature of interference.
