... scheme in this subsection. For gaining insight into the power allocation based on minimizing the SER, we are going to minimize the approximate MGF of the random variable γ, obtained in (51). Using ... demonstrates that using the power control schemes of Section 5, about 1 and 2 dB gain will be obtained for R = 2 and R = 3 cases, respectively, comparing to uniform power alloca...
