• Concept of Compatibility Region for the Evaluation of IR UWB Electromagnetic Compatibility

  Publikacja

  • R. Katulski
  • J. Sadowski

  - Rok 2014

  This paper presents a new proposal for the unified evaluation of ultra wideband and narrowband radio communication systems electromagnetic compatibility, called “compatibility region”. The idea of compatibility region is based on the relation between the ratio of narrowband to ultra wideband signal power in a receiver and some transmission quality indicators (bit error rate, effective data rate).
