讲座内容 Massive MIMO has been regarded as one of the key enabling techniques for the 5G mobile systems. To expedite the deployment of massive MIMO systems in practical networks, how to reduce the implementation cost is a critical issue to be addressed. One of the promising solutions to overcome the above challenge is to use low-resolution ADCs/DACs at the massive number of RF chains. In this talk, we focus on the multi-pair massive MIMO relaying system, and investigate the impact of coarse quantization due to low-resolution ADCs/DACs on the sum rate performance, with emphasis on the scenario with extremely low cost one-bit ADCs/DACs. In addition, non-linear precoding schemes are proposed to enhance the system performance.
