Abstract :
In this paper we consider the error performance analysis of lattice alignment for the many-to-one interference channel. An upper bound on the error probability for the first receiver when lattice codes are used is derived. More precisely, we consider the case of joint maximum-likelihood (ML) decoding of the desired signal and the sum of interfering signals, derive the union bound for the error probability in terms of the theta series of these lattices, and show that it is related to the flatness factor.
