Millimeter-Wave mMIMO-NOMA Communication System Design in a Complex Blocking Environment

The requirements for ultra-high data rates and massive connections have triggered an explosive demand for traffic, brought new challenges to 5G wireless communications, and thus promoted the vigorous development of mmWave mMIMO-NOMA communication networks. To cope with the complex blocking environment in the city, facing the challenges of multipath effects, shadow fading, and mobility management, the research on reliable transmission under the mmWave mMIMO-NOMA communication network has become the focus of research. This article first introduces the fundamental theories in mmWave mMIMO-NOMA communication networks, analyzes the key technologies and research status of mmWave mMIMO-NOMA networks, and designs mmWave mMIMO-NOMA under complex blocking environments. Subsequently, this article combines the Monarch Butterfly algorithm and resource allocation technology into the mmWave mMIMO-NOMA communication network under the complex blocking environment and forward to the future development trend.
