Author ProfileAbstract
Using Jensen's inequality and integration by parts, we derive some tight
upper bounds on the Gaussian Q-function. The tightness of the bounds
obtained by Jensen's inequality can be improved by increasing the number
of exponential terms, and one of them is invertible. We obtain a
piece-wise upper bound and show its application in the analysis of the
symbol error probability of various modulation schemes in different
channel models.26 Apr 2023Submitted to Electronics Letters 26 Apr 2023Submission Checks Completed
