A low-complexity detector for uplink massive MIMO systems based on Gaussian approximate belief propagation


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… (More)
