In this paper, an iterative multiuser detector is proposed for uplink large-scale Multiple Input Multiple Output (MIMO). It is developed based on the Generalized Approximate Message Passing (GAMP) algorithm, and its convergence properties are analyzed by a one-dimensional iteration termed as State Evolution (SE). The SE analysis proves that the complexity of the GAMP detector (GAMPd) is one order of magnitude smaller than that of the Minimum Mean Square Error (MMSE) detector. Simulation results show the GAMPd performs similarly to MMSE at least, and even outperforms the latter when the number of BS antennas is not much larger than the number of users. In addition, the GAMPd with matrix-vector multiplications is suitable for hardware implementation. |
