Y J Integration of previous expression will be carried out via Meijer-G functions defined in Wolfram http HypergeometricFunctions MeijerG . First we have to transform exponential and Bessel functions in Meijer-G functions in accordance to Wolfram http and Wolfram http . Integration is performed with Wolfram http . After some algebraic manipulations and simplifications in accordance to Wolfram http Outage Performance and Symbol Error Rate Analysis of L-Branch Maximal-Ratio Combiner for K- and T - Fading 353 and Wolfram http we obtain closed-form expression for average SEP for non-coherent detection Lạ .
