Near-Complementary Sequences With Low PMEPR for Peak Power Control in Multicarrier Communications
New families of near-complementary sequences are presented for peak power control in multicarrier communications. A framework for near-complementary sequences is given by the expl...

Characterization of SINR region for interfering links with constrained power
In this paper, a communication system including n interfering additive white Gaussian noise (AWGN) links is considered. Each transmitter uses a Gaussian codebook and each receiver...

On the Strictness of the First-Order Quantifier Structure Hierarchy over Finite Structures
One of the major interests of finite model theory is to separate the expressive power of different logics or fragments of logics. In this paper, we define a variant of EhrenfeuchtF...

Monadic second-order logic on tree-like structures
An operation M which constructs from a given structure M a tree-like structure whose domain consists of the finite sequences of elements of M is considered. A notion of automata r...
