摘要
This paper gives an outline of the algorithms and implementation of the main signal processing techniques being developed for 5G wireless communication. 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.
