    A Modified Direct-Sequence Spread Spectrum Modulation Scheme for Burst Transmissions

    The Direct-Sequence Spread Spectrum modulation (DSSS) is a very attractive modulation technique for military communication systems, mainly due to its resistance to interference and low probability of detection. However, the synchronisation to the spreading code phase in the receiver takes time, which makes this technique less interesting for sending very...

    Coexistence of Tactical Cognitive Radio Networks

    In this paper, the authors consider the scenario in which N different cognitive radio networks can not cooperate with each other and wish to broadcast a common information to their network by sharing the same Nc parallel sub-channels. This scenario is particularly adapted to tactical radio networks in which N...

    Impacts of Land Cover Data Quality on Regional Climate Simulations

    The land surface influences local, regional and global climate across many time scales. Accurate representation of land surfaces is an important factor for climate modelling studies because land surfaces control the partitioning of available energy and water. Here this paper introduce new, up-to-date and accurate land cover data for the...

    The State of the Art of Dynamic Spectrum Access

    Cognitive Radio is one of the most promising paradigms for wireless communication, as it enables a flexible use of the radio spectrum. For this, several new techniques were developed that provide a good overview about the current spectrum usage and facilitate dynamic adaptation to it. Moreover, it was investigated how...

    Towards the Provision of Site Specific Flood Warnings Using Wireless Sensor Networks

    An important aspect of flood risk management is the issuing of timely flood alerts. The spatial, as well as temporal, scale of these warnings is important. In many situations efficient risk management may be aided by the provision of local flood predictions at a high spatial resolution. Examples of such...
