The statistics of error prediction between experimental and proposed model is RMSE = 5.29, which show the high accuracy of the proposed model. Also, the proposed model was applied to the blind data, and the statistics of error prediction is RMSE = 7.76, which also shows a reasonable accuracy of the model. This model will save the time and cost on simulations and experiments, and will help in designing an accurate link budget calculation for a future enhanced system for ultra-wideband body-centric wireless systems.eninfo:eu-repo/semantics/openAccessChannel CharacterizationImplants/Wearable DevicesIn Vivo ChannelMathematical ModelingWireless Body Area NetworksArticle10.1109/ACCESS.2018.2823741620848208542-s2.0-85045183675Q1WOS:000431497000001Q2
