给出了 =10 dB时三种方案的中断概率随传输速率R变化的情况，由图可以看出，速率R越小，中断概率越小，且本文建议的方案在相同传输速率情况下，中断概率最小-Outage probability given the situation with the transmission rate R = 10 dB change when the three programs, it can be seen from the figure, the smaller the rate R, the outage probability is smaller, and the proposed solution in the same transmission rate, the interruption The minimum probability
