Abstract

The invention relates to an intelligent reflector-assisted SM-NOMA system resource allocation method, which belongs to the technical field of communication, and comprises the following steps of: for an intelligent reflector-assisted SM-NOMA system, carrying out dynamic user grouping by considering the effective channel gain of each user; and according to the maximum transmitting power constraint of the base station and the user and the incident signal phase shift constraint of the intelligent reflection unit, establishing a power distribution model taking maximization of the system sum rate as a target. The system resource allocation algorithm provided by the invention can effectively improve the system sum rate and reduce the system error rate on the premise of ensuring the maximum channel difference of each group of users.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an SM-NOMA system resource allocation method assisted by an intelligent reflection surface. Background technique [0002] With the gradual deployment of 5G network commercialization, 6G communication technology is also being explored. Intelligent Reflecting Surface (IRS), as a passive reflective array, further improves the spectrum and energy efficiency of the system by adjusting the wireless propagation environment, while reducing energy consumption and hardware costs, which has attracted widespread attention. The smart reflector is composed of a large number of small, low-cost reflective units of thin-layer electromagnetic materials, and is controlled by programmable smart devices. At the same time, the reflection of the incident signal is realized by adjusting the phase of the reflective units. The biggest difference from the traditional communication system is that it im...
