Document Type and Number:
WIPO Patent Application WO/2022/165872
Kind Code:
A1
Abstract:
Provided is a path parameter extraction method for a millimeter wave 3D MIMO channel, which belongs to the field of communication channel parameter extraction. The method comprises the following steps: S1. obtaining wireless channel measurement data, and integrating the measurement data into a channel matrix; S2. increasing the vertical dimension of a guide vector in the channel matrix in S1, and dividing path parameters to be estimated into three parameter subsets: propagation delay, horizontal and vertical angles at a transmitting end, and horizontal and vertical angles at a receiving end; S3. performing iterative operation on each path channel parameter by using a joint search policy of time delay and three-dimensional space angle, and updating channel parameters in a current parameter subset to be estimated; and S4. on the basis of the extraction result in S3, performing multi-path cluster characteristic analysis, and obtaining intra-cluster delay extension and angle extension features. The described method is suitable for extracting parameters of a millimeter wave 3D MIMO wireless channel, and can ensure the accuracy and resolution in the extraction of the parameters of a sparse multi-path channel.
