| 摘 要： | 提出了一种基于SCS(Soft-Constraint-Satisfaction)算法的盲自适应多用户检测器。基于SCS算法的盲自适应多用户检测器只需知道期望用户的扩频码及定时信息，而且通过自动选择用来估计期望信号的非线性函数，可以调节算法的收敛速度和估计误差。仿真实验表明该方法具有较好的抗多址干扰的能力。

| Abstract: | A blind adaptive multiuser detector based on SCS (Soft Constraint Satisfaction) algorithm is proposed.It only needs the timing and spreading code of the expected user.The convergence speed and estimation error can be adjusted through the choice of the nonlinear function,to estimate the expected signal.Emulation shows that the detector has good multi address resistant capability. |
