At first, the exact ASER is expressed without any approximation. In addition, we have derived the modified moment generating function (MGF) by extension of the probability density function (PDF) of the order statistic to the given relay's selection probability for OAF relay system. Then, the ASER bound to be more accurate and another ASER form of previous researches are respectively derived by utilizing the modified MGF. Furthermore, the accuracy of derived ASER bound is analytically confirmed by comparison with each other. Simulation results are finally presented to validate the analysis.
