Document Type and Number:
WIPO Patent Application WO/2023/165630
Kind Code:
A1
Abstract:
Disclosed is a method for calculating a spatial non-stationary wireless channel capacity for large-scale antenna array communication, comprising the following steps: first, constructing a spatial non-stationary channel model of a large-scale antenna array having a mutual coupling effect; building a channel measurement system for the large-scale antenna array, and obtaining measurement data; next, optimizing a parameter of the channel model, and simulating a spatial cross-correlation function; then calculating a spatial stationary interval and calculating a channel capacity and a total channel capacity within the interval; and finally comparing a simulation result with a measurement result, to verify correctness of the calculation method. The method for calculating a 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. The channel model used in the present invention has high accuracy and can be used to describe a real channel environment, and by adding a mutual coupling effect, the channel model is more in line with the characteristics a channel of a large-scale antenna array.
