Infinite Impulse Response Graph Filters in Wireless Sensor Networks

Posted on January 28, 2016 by Matlab-Projects |

Many signal processing problems in wireless sensor networks can be solved by graph filtering techniques. Finite impulse response (FIR) graph filters (GFs) have received more attention in the literature because they enable distributed…

Applications of narrow-filtering based on optical coherent detection

Posted on January 28, 2016 by Matlab-Projects |

Processing of high-frequency, wide-band signals is conveniently performed in the optical domain due to availability of optical filters which intrinsically have a wide-band response. On the other end, there are several application scenarios…

Laplacian matrix learning for smooth graph signal representation

Posted on January 28, 2016 by Matlab-Projects |

The construction of a meaningful graph plays a crucial role in the emerging field of signal processing on graphs. In this paper, we address the problem of learning graph Laplacians, which is similar…

Total generalized variation for graph signals

Posted on January 28, 2016 by Matlab-Projects |

This paper proposes a second-order discrete total generalized variation (TGV) for arbitrary graphsignals, which we call the graph TGV (G-TGV). The original TGV was introduced as a natural higher-order extension…

Simple Broadband Quasi-Optical Spatial Multiplexer in Substrate Integrated Technology

Posted on January 28, 2016 by Matlab-Projects |

We present a new type of broadband spectral-spatial quasi-optical decomposer for microwave analogsignal processing fully implemented in substrate integrated waveguide (SIW) technology. An input SIW is modulated to couple energy to a…
