Invertible Exponential-Type Approximations for the Gaussian Probability Integral Q(x) with Applications


In this article, we present very tight exponential-type approximations for the Gaussian probability integral Q(.) and/or the complementary error function erfc(.) which are subsequently used to devise the conditional symbol error probability (CEP) formulas for several classes of digital modulation schemes that are both invertible and in a "desirable… (More)
