Approximation for the Two-Dimensional Gaussian Q-Function and Its Applications
Jinah Park, Seungkeun Park · ETRI Journal · 2010
In this letter, we present a new approximation for the two-dimensional (2-D) Gaussian Q-function. The result is represented by only the one-dimensional (1-D) Gaussian Q-function. Unlike the previous 1-D Gaussian-type approximation, the presented approximation can be applied to compute the 2-D Gaussian Q-function with large correlations.
