| 摘 要： | 随着多用户检测技术研究的深入,对非正交多脉冲调制(NMM)信号的接收机的设计是非常必要的。针对非正交多脉冲调制信号多用户干扰问题,设计了一种非相干解相关接收机前端,这种接收机将多用户信道分解成K个单用户信道,这样相当于将多用户检测问题转换成噪声加强的单用户检测问题,极大地降低了问题的复杂性。仿真结果表明了此检测算法的性能优于常规检测器。

| Abstract: | It is necessary to design the receiver for NMM signal.A noncoherent decorrelative receiver front end is designed.Like its couterpart in single-pulse modulation,this front end eliminates multi-users interference.It reduces the multi-users detection problem into decoupled single-user problems over equivalent noise-enhanced single-user channels and greatly reduces the complexity of the problem.The simulation proves that it is better than conventional detection. |
