A Study on 2 D and 3 D Channel Models for Multiple Input Multiple Output Systems

Multiple Input Multiple Output Technology promises higher data rates with increased spectral efficiency. MIMO and multiple antenna technology have been adopted in IEEE 802.16e-based Mobile WiMAX systems and Long-Term Evolution Mobile wireless systems recently. The channel model is a key factor considered in the network performance evaluation. As the channel model influences network performance its characteristic (modeling) should be well defined; but as in practical case it is not possible because of its random characteristics. That is why various channel models have been proposed for different environments. This paper enlightens about the influence of correlation in channel model and the characteristics of different channel models. Different 2D and 3D Channel models have been studied and discussed.
