Abstract

We examine the problem of designing complex, equal energy, signal constellations for the noncoherent additive white Gaussian noise communication channel. We derive an asymptotic performance criterion that may be used as a constraint in building correlated signals set for use with the maximum likelihood noncoherent detector. We present an iterative update design procedure for obtaining bandwidth-efficient signal sets under a constraint on the dimension of the signal space
