    DSSS Differential GMSK With Space-Time Modulation for Robust Mobile Data Links

    A new modulation scheme combing GMSK with Direct-Sequence Spread Spectrum (DSSS) and differential modulation is proposed in this paper, which is named DS-DGMSK. The demodulation can achieve BER performance comparable to DBPSK while the bandwidth efficiency and power efficiency are higher thanks to GMSK. By combining with spread spectrum and...

    Effects Of Discretionary Fiscal Policy: New Empirical Evidence For Germany

    This paper analyses the effects of discretionary fiscal policy by presenting new empirical evidence for Germany within a Structural Vector AutoRegression (SVAR) framework. Following Blanchard and Perotti (2002), the SVAR model is identified by applying institutional information. The authors find no compelling evidence for the effectiveness of discretionary fiscal policy....

    Entity Search With NECESSITY

    Loosely structured heterogeneous information spaces are typically created by merging data from a variety of different applications and information sources. A common problem these information spaces need to address is that various data describe the same real-word entities (e.g., people, conferences, organizations). In this paper, the authors introduce NECESSITY, an...

    Does Training On Behavioral Finance Influence Fund Managers' Perception And Behavior?

    This paper provides survey evidence on the influence of training on behavioral finance on professional fund managers' perception and investment behavior. In particular, it examines whether "Trained" fund managers differ from the "Untrained" ones in their perception of markets and themselves as well as in their choice of information sources...

    Coupling Wireless Sensor Networks and the Sensor Observation Service - Bridging the Interoperability Gap

    The application of Wireless Sensor Networks (WSN) provides an inexpensive and easy to implement monitoring system for landslide events. The system used in SLEWS for deploying sensor units is constructed by the project partner ScatterWeb. As a modern and autonomous ad hoc wireless sensor network it is characterised by self-organisation...
