BER Upper Bound Expressions in Coded Two-Transmission Schemes With Arbitrarily Spaced Signal Constellations
2016
IEEE Communications Letters
The main contribution of this letter is the derivation of an upper bound BER expression, as a function of distances between signal points, for arbitrary constellations, in a generic, two-transmission scheme such as relaying, HARQ, or CoMP. The approach utilizes the product-state matrix, and thus the arbitrarily chosen constellations together with the encoders do not need to satisfy the quasi-regularity property that includes geometrical uniformity and symmetry. The channel fading is modeled
