Performance Analysis on 5G Waveform Candidates for MIMO Technologies

The exponential growth of dense users demands higher bandwidth for wireless communication system. Multimedia applications and smart device communication with existing cellular networks are facing challenges to satisfy the growing demands. To provide solutions to these challenges, researchers are investigating and improving the existing 4

generation networks to meet certain key requirements to be adopted for 5
^th
generation networks. Achieving low latency, high data rates, spectral efficacy, reduced peak to average power ratio (PAPR), interference-free transmissions, enhanced values of signal to noise ratio (SNR), less computational complexity, and offering good quality of service is the primitive motto of 5G modulation techniques. This paper describes the assessment of different 5G waveform applicants such as orthogonal frequency division multiplexing (OFDM), filter bank multi-carrier (FBMC), generalized frequency division multiplexing (GFDM) and universal filtered multicarrier (UFMC) techniques under various key parameters. In this paper, the strengths and weaknesses of each scheme are highlighted along with the flexibility of implementation with multiple input multiple output (MIMO) antenna configurations. Finally, on survey a comparison table is formed which concludes a best suitable modulation method for varieties of 5G applications.
