Linear precoder design through cut-off rate maximization in MIMO-OFDM coded systems with imperfect CSIT
This paper proposes a linear transmitter design that aims at minimizing the packet error rate (PER) using partial channel state information at the transmitter (CSIT). The design is...

Probability Density Functions of Reliability Metrics for 16-QAM-Based BICM Transmission in Rayleigh Channel
— In bit interleaved coded modulation (BICM), the probability density function (PDF) of the reliability metrics (Lvalues) fully defines the BICM transmission and may be used to ...

On the geodetic number and related metric sets in Cartesian product graphs
A set S of vertices of a graph G is a geodetic set if every vertex of G lies in at least one interval between the vertices of S. The size of a minimum geodetic set in G is the geo...

Metric Embeddings with Relaxed Guarantees
We consider the problem of embedding finite metrics with slack: we seek to produce embeddings with small dimension and distortion while allowing a (small) constant fraction of al...

Stochastic event capture using mobile sensors subject to a quality metric
Mobile sensors cover more area over a period of time than the same number of stationary sensors. However, the quality of coverage achieved by mobile sensors depends on the velocit...
