Embodiment Construction

[0039] The present invention will be further described below in conjunction with examples and accompanying drawings. It should be noted that the embodiments do not limit the protection scope of the present invention.

[0040] The purpose of the present invention is to introduce an intelligent reflection surface into the power domain NOMA system, fully excavate and utilize the limited communication resources of the system, and design an efficient communication transmission scheme.

[0041]Firstly, the power domain NOMA system model based on the intelligent reflector is modeled, and the received signal expression, detection signal-to-noise ratio and signal-to-interference-noise ratio of non-orthogonal users are given; then, the continuous phase shift of the reflector is shifted by 1-bit coding method Convert to discrete phase shift, and solve the optimal detection signal-to-noise ratio and signal-to-interference-noise ratio of the mth user under the discrete phase-shift; finally,...

Abstract

The invention belongs to the technical field of wireless communication, and provides an intelligent reflecting surface assisted power domain NOMA communication system design method, which assists a base station to send information to a non-orthogonal user by introducing a metamaterial intelligent reflecting surface. The design method comprises the following steps: establishing an intelligent reflector auxiliary NOMA system model, giving a user received signal expression and a detection signal-to-noise ratio, proposing a 1-bit coding random phase shift mechanism to convert continuous phase shift of an intelligent reflector into random phase shift, controlling a reflection unit through '1' and '0' switches, and deriving an interruption probability theoretical expression of a user. Compared with a traditional OMA system assisted by a decoding forwarding relay, an amplifying forwarding relay and an intelligent reflecting surface, the method has the advantages that the outage probability performance and the system spectral efficiency are improved, and the application value is high.

Description

technical field [0001] The invention relates to a design method of a power domain NOMA communication system based on an intelligent reflective surface, which belongs to the technical field of wireless communication, and in particular relates to a 1-bit encoding method for converting continuous phase shifts reflected on a reflective surface into random phase shifts. Background technique [0002] With the rapid growth of demand for mobile communication data services, higher requirements are put forward for key technical indicators such as spectrum efficiency and user connection density of the next generation mobile communication system. As a symbolic technology of mobile communication system upgrading, multiple access has always been widely concerned. From the first generation to the fourth generation of communication, the traditional OMA scheme is adopted, that is, the degree of freedom of wireless resources in the time domain, frequency domain or air domain is limited by the...
