摘要
提出了通过非线性优化求解线性多用户检测器中线性变换矩阵的一种方法,并分析了其性能.计算结果表明:①在理想功率控制条件下,这种检测器的误比特率小于传统多用户信号检测器和解相关多用户信号检测器的误比特率;②在抗“远—近”效应方面,这种检测器强于传统检测器。
This paper presented a method to obtain the matrix in linear multiuser signal detector through solution of a nonlinear optimization problem, and gave its performance analysis. Numerical results show that ①under ideal power control, in aspect of bit-error rate, the optimum linear multiuser signal detector is better than the conventional and decorrelated multiuser signal detectors;②in aspect of 'near-far' resistance, the optimum linear multiuser signal detector is better than the conventional one, and is worse than the decorrelated detector.
