Abstract
In this paper, capitalizing on novely introduced interval approximation of Q-function, we have presented simple and tight approximation for the evaluation of the average symbol error probability (ASEP) over fading channels. First, comparison to other known Q-function closed-form approximations has been performed, and it has been shown that accuracy improvement has been achieved by using proposed interval approximation in whole range of input values. Further, it has been shown that by using proposed approximation, values of ASEP for some applied modulation formats could be efficiently and accurately evaluated when transmission over fading channels is observed. Also has been shown that than by using proposed approximation, ASEP measures are bounded more closely than by using other known Q-function closed-form approximations.
