The first part contains a review and comparison of six orthogonal and nonorthogonal waveformgeneration and modulation schemes： generalized frequencydivision multiplexing （GFDM）, filterbank multicarrier （FBMC）, universal filtered multicarrier （UFMC）, biorthogonal frequencydivision multiplexing （BFDM）, sparsecode multipleaccess （SCMA）, and nonorthogonal multiple access （NOMA）. The second part discusses spatial signal processing algorithms and implementations for massive multipleinput multipleoutput （massiveMIMO）, 3D beamforming and diversity, and orbital angular momentum （OAM） based multiplexing. The last part gives an overview of signal processing aspects of other emerging techniques in 5G, such as millimeterwave, cloud radio access networks, full duplex mode, and digital radiofrequency processing.展开更多

The related technol?ogies for 5G NR can mainly be categorized into four areas, namely, 1) new mod?ulation and coding algorithms including multi?user superposition and shared access, enhanced waveform generation and advanced error?correction coding;展开更多

With 2G, 3G and 4G, the peak service rate is the dominant metric that distinguishes these three generations. 5G will significantly increase the peak service rate but will also dramatically increase energy efficiency, frequency efficiency, spectral effi- ciency, and efficiency of other resources. It will dramatically increase flexibility, ca- pacity, coverage, compatibility and convergence. In this way, it will salisfy the in- creasing demands of emerging big-data, cloud, machine-to-machine, and other ap- plications. The successful development and deployment of 5G technologies will be challenging and will require huge effort from industrry, academia, standardizalion organizations, anti regulatory authorities.展开更多
