摘要：
In this paper, a new receiver that jointly and blindly estimates the channel parameters and the transmitted symbols in a multiuser cooperative diversity scheme is proposed. The receiver is based on the canonical polyadic (CP) decomposition of a tensor composed of received signals with dimensions associated with space (receive antennas), slot (cooperative channel) and time (symbol period). The receiver fits the tensor model using the Levenberg-Marquardt (LM) algorithm, assuming that channel state information (CSI) is not available at the relays neither at the base station. The performance of the proposed receiver is evaluated by means of computer simulations.
