Embodiment

[0042] like figure 1 Therefore, a modeling method of orthogonal channel matrix is ​​proposed, which includes the following steps:

[0043] The antenna correspondence of multiple base stations or multiple terminals is regarded as one base station or one terminal, and the orthogonal channel modeling of the end with fewer antennas is realized;

[0044] The basic square matrix is ​​defined as:

[0045]

[0046] The concatenated square matrix is:

[0047]

[0048] Assuming that an M×N orthogonal channel matrix needs to be generated,

[0049] When M>N,

[0050] (1) First calculate the M×M orthogonal channel matrix, assuming M=2 q , q∈[1,+∞), and q is a positive integer, suppose p∈[1,q], and p i is an element in the vector p, i∈[1,2,…,N], we know that p N =q;

[0051] (2) If p i The orthogonal channel matrix of , then

[0052]

[0053] Wherein B(1,1) represents the element of the first row and first column in the spliced ​​square matrix B;

[0054] (3) If p i+1 ≤...

Abstract

The present invention relates to the technical field of wireless channel modeling; currently commonly used orthogonal channels are used for orthogonal channel modeling for a single base station or a single terminal, and there is no orthogonal channel for realizing arbitrary dimensions for multiple base stations or multiple terminals. The present invention proposes a modeling method of an orthogonal channel matrix, and realizes an orthogonal channel modeling method at one end with fewer antennas, that is, channel orthogonality on the base station side or the terminal side can be realized. It has the advantages of simple implementation, simple principle, and unlimited expansion Advantages; generate an orthogonal channel matrix modeling method of any specified dimension, that is, based on the orthogonal principle of the triangular coordinate system, it can realize orthogonal modeling of any dimension.

Description

technical field [0001] The invention belongs to the technical field of wireless channel modeling, and in particular relates to a modeling method of an orthogonal channel matrix. Background technique [0002] In MIMO wireless channel modeling, orthogonal channel is a very special channel model. MIMO communication system will affect its channel capacity due to the existence of fading channel, but orthogonal channel, as a theoretically existing channel model, can help MIMO communication system reach the peak channel capacity, and this value can be used as the upper bound of subsequent fading channel capacity test To guide the subsequent system optimization and wireless channel testing, so it is a key part of the channel emulation test. Orthogonal channels commonly used at present are all orthogonal channel modeling for a single base station or a single terminal, and there is a lack of orthogonal channels that implement arbitrary dimensions for multiple base stations or multipl...
