摘要：
In a long-code uplink CDMA system, subspace method is recently proposed to estimate all users' multipath parameters and noise power based on the correlation matrix of whitened data. In this paper, we focus on performance of three typical linear receivers, known as zero-forcing (ZF), minimum mean-square-error (MMSE), and RAKE receivers, constructed from the estimated channels and noise power. All analyses are performed from a perturbation perspective and verified by our numerical examples.
