In this paper, we propose a semiblind multiuser detection framework for asynchronous CDMA. Compared with most existing semiblind/blind detectors, the proposed framework requires a minimum number of previously received signals, which is about the number of interfering signals, and no detection filter converging or sub-space separation procedure. The computational complexity and detection delay are...
We propose a new blind multiuser signal model and detection framework for solving the near-far problem in synchronous CDMA in this paper. Compared with existing blind detectors, the proposed framework requires a minimum number of previously received signals, which is about the number of interfering users, and no sub-space separation or sequence estimation. Hence its computation complexity and detection...
