  • ALOE: an open-source SDR execution environment with cognitive computing resource management capabilities 

    Gómez Miguelez, Ismael; Marojevic, Vuk; Gelonch Bosch, Antonio José (2011-09)
    Article
    Restricted access - publisher's policy
    Future radio transceivers will offer more functionalities and system features for potentiating flexible and reconfigurable radio access networks. Since flexibility in this case comes at a price of computing resource overhead, ...
  • Analyzing the effect of power control algorithms on the receiver's computing resource consumption 

    Gómez Miguelez, Ismael; Marojevic, Vuk; Salazar Hernández, Dagoberto José; Gelonch Bosch, Antonio José (2010)
    Conference report
    Restricted access - publisher's policy
    Traditional Software-Defined Radios are limited in their ability to share the computational infrastructure between different channel flows of different demands. Future terminals should move to a shared resource model to ...
  • Automatic computing resource awareness in resource managers for cognitive radios 

    Gómez Miguelez, Ismael; Marojevic, Vuk; Gelonch Bosch, Antonio José (2010)
    Conference report
    Open Access
    With all the potential flexibility of software-defined radios, the flexibility of SDR terminals is currently limited to design time flexibility. The capacity of the platform in terms of processing resources and internal ...

    Article
    Open Access
    Software-defined radio (SDR) describes radio transceivers implemented in software that executes on general-purpose hardware. SDR combined with cloud computing technology will reshape the wireless access infrastructure, ...
  • Middleware extension for partial reconfiguration management in cognitive radios 

    Gómez Miguelez, Ismael; Wang, Honhzhi; Nafkha, Amor; Marojevic, Vuk; Moy, Christophe; Leray, Pierre; Gelonch Bosch, Antonio José (2010)
    Conference report
    Restricted access - publisher's policy
    Today’s radio access technologies demand flexible, high performance and power-efficient computing. Software-defined radios offer a high degree of flexibility but their performance is limited in energy-constrained environments. ...
  • Performance and overhead analysis of the ALOE middleware for SDR 

    Gómez Miguelez, Ismael; Marojevic, Vuk; Bracke, Jordi; Gelonch Bosch, Antonio José (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
    Conference report
    Open Access
    Current Software-Defined Radio applications (waveforms) are tailored to specific hardware. Processor vendors frequently adapt internal OS mechanisms for its specific architecture (e.g. scheduling and synchronization). ...
  • Processing-to-amplifier power ratio for energy efficient communications
