适用于多径信道环境下的基于子空间的UID
Subspace-Based UID in Multipath Channels
【摘要】 针对传统的基于子空间方法的用户识别检测器(UID)在多径信道环境下性能恶化的问题,基于重新构造的包含多径信道信息的信息序列矩阵,提出了一种新的基于子空间的UID.仿真结果证明,在多径信道和强"远-近效应"环境下,该UID可以保证较低的误警概率.
【Abstract】 For the problem of performance degradation of the traditional subspace-based user identification detector (UID) in multipath channels, based on the reconstructed signaling sequence matrix that includes the information of multipath channels, a new subspace-based UID was proposed. The simulation result shows that the proposed UID will be ensure a low false-alarm rate in both the multipath channels and heavy "near-far effect" environments.
