However, in the CDMA system, due to the sharing of frequency resources among multiple users, interference between users has become a key issue. To address this issue, interference cancellation and multi-user detection techniques have been proposed to improve the communication quality and capacity of the system.This paper focuses on the interference cancellation and multi-user detection techniques in CDMA mobile communication, and discusses the principles and applications of this technology. Firstly, the paper will introduce the principles of CDMA system and multiple user access technology. Then, it will elaborate on the classification and implementation principles of interference cancellation technologies, and explore the advantages and disadvantages of different interference cancellation techniques. Finally, it will introduce the principles and applications of multi-user detection techniques, and discuss their combination with interference cancellation techniques.By studying interference cancellation and multi-user detection techniques in CDMA mobile communication, this paper provides an effective solution to improve the communication quality and capacity of the system.Keywords: CDMA mobile communication, interference cancellation, multi-user detection, communication quality, capacity.
