Abstract :
Variation of the path gain in on-body transmission channels is investigated in several realistic scenarios. Short-term and long-term fading statistics are investigated and non-stationarity of both the types of fading in indoor multipath environments is demonstrated. It was found that the short-term fading is best described by a Rician distribution with the K-value log-normally distributed, and a gamma distribution is best suited for the long-term fading.
