Embodiment Construction

[0048] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0049] like figure 1 As shown, a downlink NOMA transmission method based on dual-polarization MIMO, including a signal alignment-based beamforming method and a genetic algorithm-based power and polarization state allocation method.

[0050] The system framework of a downlink NOMA transmission method based on dual-polarization MIMO provided by the present invention is as follows: figure 1 As shown, the system framework is divided into three parts: entity layer, policy layer and evaluation layer.

[0051] (1) Entity layer, involving main entities participating in the communication system, including a base station and multiple users. Considering that the transmission scenario is a downlink scenario, the base station has the channel state information of each user, and the base station is equipped with M co-point dual-polarized antennas, cor...

Abstract

The invention provides a downlink NOMA transmission method based on dual-polarization MIMO. The downlink NOMA transmission method comprises a beam forming method based on signal alignment and a powerand polarization state distribution method based on a genetic algorithm. The method has the beneficial effect that the spectrum efficiency can be improved through distribution of polarization domain resources.

Description

technical field [0001] The present invention relates to a NOMA transmission method, in particular to a downlink NOMA transmission method based on dual-polarization MIMO. Background technique [0002] The 5G standard has high requirements on the existing network. For different transmission business scenarios, such as massive data transmission, Internet of Things, Internet of Vehicles and other scenarios, it has high requirements on transmission rate, connection density, and end-to-end delay. indicator requirements. In order to meet the above performance requirements, it is very important to study related technologies such as massive MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output technology), non-orthogonal multiple access (NOMA), and millimeter wave technologies. There are many existing researches on NOMA technology based on single polarization, and these researches are mainly divided into three parts: 1. User pairing. Since NOMA technology adopts seri...
