Multi-user HAP-MIMO channel model building method based on birth and death process

The invention provides a multi-user HAP-MIMO channel model building method based on a birth and death process, and the method comprises the steps: respectively employing 0 and 1 for representing the visible and invisible states (relative to an antenna unit) of a scatterer. For different users, because the positions and surroundings of the users are different, the same scatterer has different states for different users; for the same scatterer, the scatterer has the appearance and disappearance non-steady characteristics relative to different antenna units. The method employs the birth and death process to describe the appearance and disappearance non-steady characteristics of the scatterer, and gives consideration to a condition that a disappeared scatterer appears again. The method gives consideration to a more practical scene, so the method can achieve the better description of the attenuation conditions of an actual channel. 本发明提供了种基于生灭过程的多用户HAP-MIMO信道模型建立方法，分别采用0和1来表示散射体可见和不可见(相对于天线单元而言)的两种状态。对于不同的用户而言，鉴于用
