RETRACTED: A new 3D statistical method for mobile channel model (Retracted Article)

3-dimension statistical method is used to simulate the popular micro-cell propagation model: COST231-Walfish-Ikegami model[6][7]. The extended model allows for improved path loss estimation by consideration the character of the urban environment parameters are lognormal random variables rather than deterministic. The numerical calculation results and trial measurement data is presented. Based on the measurement and modelling results, we find that the 3D COST231-WI model fits very well with the measurement result in the metropolitan scenario. The conclusion is useful and helpful to network planning in the future. (C) 2011 Published by Elsevier Ltd.
