Computing the Transitive Closure of a Union of Affine Integer Tuple Relations
Abstract. This paper proposes a method to compute the transitive closure of a union of affine relations on integer tuples. Within Presburger arithmetics, complete algorithms to com...

A stochastic memoizer for sequence data
We propose an unbounded-depth, hierarchical, Bayesian nonparametric model for discrete sequence data. This model can be estimated from a single training sequence, yet shares stati...

Probabilistic Analysis of the Semidefinite Relaxation Detector in Digital Communications
We consider the problem of detecting a vector of symbols that is being transmitted over a fading multiple?input multiple?output (MIMO) channel, where each symbol is an ?th root of...

A Detection Algorithm for Clipped OFDM Signals Using the IDFT-Matrix
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...

Detection of Gaussian constellations in MIMO systems under imperfect CSI
Abstract—This paper considers the problem of Gaussian symbols detection in MIMO systems in the presence of channel estimation errors. Under this framework we develop a computatio...
