摘要翻译：
本文利用深度神经网络(DNN)对大规模多输入多输出(MIMO)系统的信度传播(BP)检测进行了改进。首先通过对BP算法的展开，提出了一种适用于检测任务的神经网络结构。然后基于两种改进的BP检测器，即阻尼BP和最大和BP提出了DNN MIMO检测器。通过深度学习技术优化算法中的校正因子，以提高检测性能。数值结果表明了DNN检测器与各种BP改进算法的性能。神经网络训练一次，可用于多次在线检测。结果表明，与现有的检测器相比，DNN检测器在相同的复杂度下，可以获得较低的误码率(BER)，并提高了对不同天线配置和信道条件的鲁棒性。

英文摘要：
  In this paper, deep neural network (DNN) is utilized to improve the belief propagation (BP) detection for massive multiple-input multiple-output (MIMO) systems. A neural network architecture suitable for detection task is firstly introduced by unfolding BP algorithms. DNN MIMO detectors are then proposed based on two modified BP detectors, damped BP and max-sum BP. The correction factors in these algorithms are optimized through deep learning techniques, aiming at improved detection performance. Numerical results are presented to demonstrate the performance of the DNN detectors in comparison with various BP modifications. The neural network is trained once and can be used for multiple online detections. The results show that, compared to other state-of-the-art detectors, the DNN detectors can achieve lower bit error rate (BER) with improved robustness against various antenna configurations and channel conditions at the same level of complexity.
