Moment generating function of Gamma distribution
Webb, For independent Nakagami-m fading channels, it is assumed that each of the band channels has Nakagami-m , (10) distribution, which implies that an instantaneous for each band will have gamma distribution. Therefore, the MGF is defined in [14] and can be written in terms of the where is the moment generating function (MGF) and it is here. WebbThe joint moment generation (mgf) and characteristic functions of given in Equation ( 6) are (8) and (9) respectively. Assuming , thus and , which are the mgf’s of a gamma random variable. The proof of the characteristic function of is trivial, following the proof of Proposition 1 for . Proposition 2. Webbof converting a MGF back to a distribution is to look it up on a table of MGFs of known distributions and recognize it as the MGF of a known distribution. For example, if we … fish michael phd
