摘要 在同步码分多址(SCDMA)系统接收机中,基于天线阵列的级联干扰消除多用户检测器能够补偿用户特征波形间的非零互相关性。仿真比较表明,该方案性能优于常规检测器与单天线干扰消除器,可以克服远近效应,抑制多址干扰,明显提高系统容量。 The nonzero crosscorrelations between the users?signature waveforms can be compensated by the successive interference cancellation multi-user detector (SIC-MUD) based on antenna arrays in the receivers of SCDMA systems. The comparison of simulation displays that performances of SIC-MUD are better than conventional detectors and single antenna interference cancellers, and thus they are able to overcome near-far effect, suppress MAI, and increase the system capacity significantly.
