N2 - With the advent of the 5G era, massive device access and explosive data traffic grow rapidly, it is imperative to improve network throughput. As a new network architecture, Cell-Free Massive MIMO can effectively improve network throughput. MUSA (Multi-user shared access), as a kind of NOMA (non-orthogonal multiple access technology), has a great gain in spectrum efficiency. Integrating MUSA’s related technologies into the Cell-Free Massive MIMO system can effectively improve the spectrum efficiency and meet the massive access requirements. In this paper, by using MUSA, the Cell-Free Massive MIMO system is improved. A clustering method is proposed. Each cluster corresponds to a pilot. Users in the cluster use MUSA to distinguish and detect multi-users. For the new model, theoretical analysis and simulation of spectrum efficiency are carried out. The results show that the improved Cell-Free Massive MIMO system has better spectrum efficiency.
