A Low-Complexity Real-Time 3-D Sonar Imaging System With a Cross Array

Posted on January 28, 2016 by Matlab-Projects |

The development of real-time 3-D underwater imaging is restricted by the huge hardware cost and the computational burden associated with a large number of transducers. In this paper, a low-complexity…

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…

ReLiSCE: Utilizing Resource-Limited Sensors for Office Activity Context Extraction

Posted on January 28, 2016 by Matlab-Projects |

The capability to extract human activity context in a room environment can be used as meaningful feedback for various wireless indoor application systems. Being able to do so with easily…

A Low-Voltage 35-GHz Silicon Photonic Modulator-Enabled 112-Gb/s Transmission System

Posted on January 28, 2016 by Matlab-Projects |

We present a silicon photonic traveling-wave Mach-Zehnder modulator operating near 1550 nm with a 3-dB bandwidth of 35 GHz. A detailed analysis of travelingwave electrode impedance, microwave loss, and phase…

On the distributed acoustic sensing based on local time-frequency coherence analysis

Posted on January 28, 2016 by Matlab-Projects |

This paper outlines novel approaches to design a new generation of distributed networks of acoustic sensors. The key-concept is marked by the use of time-frequency signal analysis tools directly embedded at the…

A novel approach for features extraction in physiological signals

Posted on January 28, 2016 by Matlab-Projects |

The authors have investigated a novel processing technique, which allows to measure possibly relevant features in the ECG (Electrocardiogram) signal according to the morphology of its waveform. The aim of this work is to…
