The project is to develop M2M MIMO channel models and parameters based on the joint theoretical researches and measurements from real environments, in where the terminals at the transceiver are moving with the same heights and located at the environments. The theoretical modeling is to develop a geometry-based stochastic model in a unified coordination system. The model is relevant to the array responses, delay, Doppler shift, angle-of- departure, angle -of-arrival and son on. A SAGE algorithm based software is to be developed to process the measured datum from the measured environments to get the statistical distributions of the channel parameters, and further to investigate the channel characteristics and propagation mechanisms. By using the channel model and generated channel parameters, the channel simulation can be realized. The channel model is further modified by comparing with simulation and measurement results. The topics of this research include: the M2M MIMO radio channel characteristics and propagation mechanisms, the geometry-based stochastic M2M MIMO channel model,the statistical distributions of the channel parameters,the empirical models for pathloss and fading, the tapped-delay-line channel models, and the channel realizations.This work will have critical application prospect in the link and system level simulations as well as the system design for the end-to-end cooperative communications in the internet -of-things and 4G wireless systems.
