High-order quadrature amplitude modulation (QAM) signals typically requires high-precision ADC at the receiver for reliable detection. However, in massive multiple-input multiple-output (MIMO) systems, the power consumption and hardware cost can be unaffordable due to the high complexity of conventional signal detectors and the associated high-precision ADC required by each antenna. To solve this...
In massive multiple-input multiple-output (MIMO) systems, the number of base station (BS) antennas could reach tens or even hundreds, therefore the hardware cost of adopting conventional signal detectors can be unaffordable due to their high complexity which increases quickly with the number of the transceiver antennas. To solve this problem, this paper proposes a low-complex iterative detector based...
