Abstract: A method for calculating the spatial non-stationary wireless channel capacity for large-scale antenna array communications, includes the following steps: first, constructing a spatial non-stationary channel model with a large-scale antenna array having the mutual coupling effect; building a channel measurement system for the large-scale antenna array, and obtaining measurement data; next, optimizing parameters of the channel model, and simulating the spatial cross-correlation function, then calculating the spatial stationary interval and calculating the channel capacity within the interval and the total channel capacity; and finally comparing simulation results with measurement results, to verify the correctness of the calculation method. The method for calculating the channel capacity of a spatial non-stationary large-scale antenna array provided in the present invention can be effectively applied to a channel having non-stationary characteristics, thereby solving the limitation of Shannon channel capacity formula calculation.
