摘　　要：本文基于旋转正交法的思想提出了新的同步ＣＤＭＡ次优化多用户检测技术，它降低了接收器的检测运算量，克服了其他同类型检测器在运算中不收敛以及重复选点而降低检测运算效率等问题，并且降低了检测误码率，新的次优化检测器还能根据信号环境及检测概率预先设置它的运算次数．In this paper,we develop a new near optimum detector especially for synchronous code division multiple access system.The detection method is based on rotating orthogonal method algorithm for 0 1 programming,and the new detector is proved to be more effective than some of other optimum (or sub optimum) detectors.With the increase of user's numbers,its complexity of calculation is O(m) in a specific statistical sense and can be controlled under different conditions.
