Multiple input multiple output channel model based on the array manifold separation technique

An array independent stochastic multiple input multiple output(MIMO) channel model is established based on the three dimensional array manifold separation technique.By expanding the array steering vector in spherical harmonics,the antenna array and the wireless propagation environment are separated.Then an array independent analytical MIMO channel model is obtained by individually modeling the wireless propagation channel based on the concept of spatial correlation.The new model is suitable for MIMO system evaluation,analysis and design.Cylindrical arrays and spherical arrays are used in simulations to demonstrate the correctness and effectiveness of the proposed channel model.
