Abstract

In the 5G system for the Internet of Things (IoT), the detection and identification of a large number of IoT users or devices has become a key issue in the research of IoT technology. In the multi-user detection algorithm based on 5g technology, due to the slow convergence speed and high complexity of the traditional algorithm, people began to consider the conditions of adding serial and threshold to study, in order to improve the performance of multi-user detection in the IoT based on 5G. In this paper, based on the research of Maximum logarithm Message Passing Algorithm (Max-log-MPA) based on threshold, the serial condition setting is added to analyze the performance of Max log MPA algorithm based on serial and threshold (S-T-Max-log-MPA) and Max-log-MPA algorithm based on threshold (T-Max-log-MPA), so as to obtain a better multi-user detection algorithm based on 5G in the Internet of things. The simulation results show that the S-T-Max-log-MPA algorithm has lower bit error rate and better performance in the experiment, which is more suitable for multi-user detection in the Internet of things based on 5G.
