  • Abstract
    We present a necessary condition that optimum two-dimensional signal constellations, used over an additive white Gaussian noise (AWGN) channel, must satisfy. Our condition is contrasted with another condition previously mentioned in the literature. A constellation of five signal points is given as an example. It is shown that the five points comprise the vertices of three equilateral triangles.
