Multiuser Channel Estimation for Detection for Cochannel Signals in the Receiver of TETRA Digital trunked System
Xin Sun, Qing An Huang · 2006
In this paper, a pilot-based MMSE technique is proposed for estimating the channel impulse responses of multiple co-channel users in the receiver of TETRA digital trunked system. Based on signal and channel models of TETRA digital trunked system, it allows time variation of the channels with and between the training sequences. The performance of this method is verified by simulations
