With the growth of user numbers and demand, the performance and reliability of communication systems have become more and more important. At the same time, interference in mobile communication is also a serious challenge. CDMA mobile communication system is a commonly used communication system. Traditional algorithms often have many problems in interference cancellation, and advanced algorithms such as parallel processing technology need to be introduced for cancellation.
