Fig. 5From: Modeling and performance analysis for mobile cognitive radio cellular networks a–c CHT statistics as a function of the interruption probability for different distributions of the UST when CDT is exponentially distributed. In this figure, red, blue, yellow, and green lines represent the scenarios where the UST is exponentially, Erlang, hyper-exponentially of order 2, and hyper-Erlang of order (2, 2) distributed, respectively. Solid-lines (dashed-lines) corresponds to CHTn (CHTh) statisticsBack to article page
