【摘要】 高阶累积量是抑制有色噪声的一个有效方法。通过分析跳频多址信号,提出了高斯有色噪声背景下的一种基于峭度的跳频盲多用户检测算法,它几乎不需要任何关于有色噪声的先验信息。仿真结果表明,该多用户检测算法收敛速度快,输出信干比较高。抗多址能力大大优于传统的子空间算法。更多还原

【Abstract】 The Higher-Order cumulant is an effective method to restrain colored noises.On the basis of the analyzing of frequency hopping multiple access(FHMA) signals, a blind multi-user detection based on kurtosis is proposed in colored noise.The method don’t need any priori information about the colored noise.Simulation results indicate that the proposed multi-user detector converges quickly,and its output BER performance is better than the subspace-based detectors.更多还原
