Channel Characteristics Modeling Based on Measurement

In-body channel models of WBAN s are gaining great interesting as they innovation application in heal-care services, military and amusement areas. In the paper, we present a study base on experimental investigation and simulation results. A seven-state semi-Markov model, which including the line-of-sight state, the shadowed state and the blocked state, is proposed. The model parameters are derived from data of measurements. Simulation results of the proposed model match well with the statistical analysis of the measured data, which provide the effectiveness and reliability of the semi-Markov channel model.
