In this paper, a massive multiple input multiple output downlink scenario is considered where the number of users varies in a large dynamic range. An adaptive joint precoding and pre-equalization with reduced complexity is proposed. Specifically, the successive over-relaxation method is employed in the pre-equalization process to avoid the high-dimensional channel matrix inversion, and a reduced-length feedback filter is proposed to reduce the computational complexity of the precoding. Moreover, an adaptive transceiver structure is proposed to switch on/off the precoding process so that multiple users can be accommodated with the least cost of the computational complexity. Simulation results show that, compared with the traditional scheme, the proposed adaptive joint precoding and pre-equalization can save about 90% of the computational complexity.
