Analysis of a modified MIMO multi-bounced channel model for narrow street environment
Published 2017-10-01“…To establish scattering models that match realistic street transmission scenarios for more efficient M2M mobile communication systems,existing models mainly focus on single-scattering and double-scattering,while for narrow urban street environment,single-scattering assumption is rather restrictive.To overcome this problem,a modified multi-bounced channel model based on EBSBM was provided,in which the concept of equivalent scattering point is assumed.The multi-bounced propagation paths are considered as an one-bounced ellipse scattering path and characteristics of the model were further analyzed.General formulations of several important parameters such as the probability density function (PDF) of the angle-of-departure(AOD),angle-of-arrival (AOA) and Doppler shift were derived,which were applied to the performance of multiple-input-multiple-output(MIMO)system employing a circular array antenna.Doppler frequency distribution was also taken into account.The results show good agreement with the previously models,which validates the rationality of proposed model.…”
