Prompt Rate Adaptation in WiMedia Considering Time Variant UWB Channels

  title={Prompt Rate Adaptation in WiMedia Considering Time Variant UWB Channels},
  author={Karsten Schoo and Janne Tervonen},
  journal={2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications},
In this paper the performance of the rate adaptation scheme specified by the WiMedia Alliance is investigated and a new, fast link feedback mechanism is proposed, which can be implemented without major modifications of the existing WiMedia UWB standard. After introducing the considered link adaptation mechanisms, a time variant UWB channel model is derived. Basic properties of UWB channels are summarized and the widely used IEEE 802.15.3a channel models are enhanced with respect to correlated… CONTINUE READING
