Abstract:A new algorithm is proposed about the research on classification assisted with Multi-user Detection based on MMSE. This paper is divided into two parts. Firstly, we analyzes the MMSE multi-user detection algorithm, and measures its performance through different SNR and other indicators. After that, a new signal modulation classification algorithm is proposed, which used the fuzzy density to fuse multiple classifiers and improve the reliability. And using the Matlab simulation to verify the performance.
