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.
