Asymmetric geometrical-based statistical channel model and its multiple-input and multiple-output capacity

One of the fundamental research areas in wireless communications is the development of realistic models that can efficiently and accurately describe the wireless propagation channel. In this paper, the authors developed an asymmetric geometrical-based statistical channel model for mobile system and investigated the multiple-input and multiple-output (MIMO) receiving performance. This work was first in the asymmetric geometry literature to derive the closed-form explicit formulae for the time-of-arrival and the angle-of-arrival of the multi-paths, then the Doppler spectra. The channel model assumed that each multi-path component of the propagating signal undergoes only one bounce travelling from the base station (BS) to the mobile station (MS) and the scattering objects distributed around the BS, are assuming Gaussian and exponential spatial distribution models. Using the channel model, the authors first analysed the performance of MIMO antenna systems and Doppler spectra because of MS´s motion.
