    Although cognitive radios has seen an enormous interest from various research communities, arguably even the definition of what it is still not clear. In particular, depending on the person's background the adapted definition varies: For example, RF antenna/reconfigurable hardware community treats it as an upgrade of an software-defined radios (SDR's), PHY/MAC and communication theory researchers ...

    This paper describes a custom-built UHF RFID-Reader-Device with functionality to send and receive EPCglobal custom commands. It can be used to access enhanced capabilities in transponders, for example readout of integrated sensors. The device was implemented using a Xilinx FPGA and is fully controllable from a PC through a customizable MATLAB-Interface. This enables a step by step test of newly de... View full abstract»

  • A heterodyne 77-GHz FMCW radar with offset PLL frequency stabilization

    This contribution describes the realization of a heterodyne frequency-modulated continuous-wave (FMCW) radar system operating in the frequency band from 76 GHz to 77 GHz. To implement the heterodyne principle two voltage controlled oscillators (VCOs) are operated in order to produce frequency ramp signals with a fixed frequency offset. This allows to mitigate effects occurring in homodyne systems ... View full abstract»

    Methods to estimate Directions of Arrival (DOA) on radio signals are susceptible to hardware and signal deficiencies. In the following, the robustness of four algorithms is evaluated by numerical and experimental tests. The focus lies thereby on Secondary Surveillance Radar (SSR) signals, but the algorithms can generally be used on any kind of radio signal. It will be shown that variants of the ES...

    A software-defined multifunctional radar sensor is developed in this paper for linear and reciprocal displacement measurement. Experiments were performed to demonstrate the high accuracy of the two measurement methodologies. When configured in arctangent-demodulated interferometry mode with a 5.46 GHz carrier frequency, the sensor can measure the displacement with sub-millimeter error at a detecti... View full abstract»

    This paper will provide a brief survey of the origins of RF-based location technology through the beginning of the Second World War. Direction finding (DF) was invented by John Stone Stone in 1902 and improved upon by Lee de Forest, Ettore Bellini and Alessandro Tosi. Both radar and amplitude ranging date to 1904, although these concepts were in advance of the ability of RF technology to implement... View full abstract»

  • Numerical and experimental investigation of TDOA-based positioning system by ultra-wideband impulse radio

    Publication Year: 2011, Page(s):25 - 28
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (213 KB) | HTML iconHTML

    This paper describes a TDOA-based positioning system by means of ultra-wideband impulse radio (UWB-IR). The system consists of three reference nodes and a location server. One of the reference nodes transmits an impulse signal to other reference nodes for synchronizing them immediately after receiving an impulse signal sent from a target node. Thus, no additional component for the synchronization ... View full abstract»

    This paper describes research into determining the 3D position of a flow follower in a confined space. The flow follower is able to transmit ultrasonic signals to receivers that are fixed to the wall of the vessel. A key challenge is to accurately determine the location of the flow follower. Transducers must be small, low power and low cost. The present work explores modifications to the Time Diff... View full abstract»
