摘要 提出了一种VBLAST的解码算法:组平行干扰抵消GPIC,利用组干扰抑制GIS把系统分解为多个子系统,简化了接收机的复杂度,同时利用多用户检测中的平行干扰抵消PIC(parallelinterferencecancellation),通过增加组间和组内干扰抵消的迭代次数来提高系统的性能.仿真结果表明该算法获得了较好的性能. In this paper, a new detection algorithm for VBLAST——GPIC(group parallel interference cancellation)——is proposed. The detection algorithm of VBLAST, called OSIC (ordered successive interference cancellation), uses linear combination nulling and successive symbol cancellation based on inversing and ordering. The computation complexity is high. GPIC proposed in this paper uses GIS (group interference suppression ) to divide a system into several small systems to simplify the receiver and uses PIC to improve performance. The simulation results show that the scheme has a good performance.
