    System Architecture in Cognitive Radio Networks Using a Radio Environment Map

    Cognitive Radio (CR) is considered as a promising solution to improve wireless spectrum utilization. Moreover, through optimization frameworks, Radio Resource Management (RRM) procedures are designed to enhance the efficient utilization of resources in CR networks. To face this issue in a holistic perspective, the RRM solutions should take into account...

    Minimal Model Of Financial Stylized Facts

    In this paper, the authors afford the statistical characterization of a linear Stochastic Volatility Model featuring Inverse Gamma stationary distribution for the instantaneous volatility. They detail the derivation of the moments of the return distribution, revealing the role of the Inverse Gamma law in the emergence of fat tails, and...

    Hybrid ARQ Based on Rateless Coding for Wireless Mesh Networks

    This paper shows an incremental redundancy Hybrid Automatic Repeat Request (HARQ) scheme, based on rateless coding, for possible application to a distributed wireless network. The proposed approach is demonstrated to be effective under energy consumption and rate constraints. This objective is pursued by increasing the average throughput, limiting the length...
