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 4th generation networks to meet certain key requirements to be adopted for 5th 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.

In this paper, performance analysis of orthogonal frequency division multiplexing (OFDM) as well as offset quadrature amplitude modulation (OQAM)/ filter bank multicarrier (FBMC) based communication network is carried out under the influence of vehicular channels. The vehicular channel models such as vehicular A and vehicular B are considered for this investigation. Further, the effect of prototype filter PHYDYAS on performance of the above mentioned networks is examined. Zero forcing (ZF) equalizer is deployed at the receiver for signal reconstruction. It is observed that OQAM/FBMC outperforms OFDM in high mobility condition whereas under low mobility conditions, their performances are almost identical.

Performance Analysis of FBMC over OFDM for High Data Rate MIMO Configurations

OFDM (Orthogonal Frequency Division Multiplexing) system has prevailed as one of the most eminent multicarrier technique in 4G wireless communication. The purpose of this paper is to overthrow the drawbacks of OFDM and investigate new candidate waveform Filter Bank Multicarrier (FBMC) which is more compatible for 5G wireless communication through their performance results. Because of achieving sharper PSD, better BER performance curve and lower PAPR need to discard Cyclic Prefix (CP) with the help of Filter Banks. To alleviate ISI (Inter-Symbol-Interference) and ICI (Inter-Carrier-Interference), this paper focuses the working procedure about OQAM processing, spreading frequency and extended IFFT/FFT and it reveals how the filter banks are responsible to improve the system performance of FBMC. Consequently, simulation based results of FBMC have exhibited that the desired solution evidently outperforms OFDM schemes in terms of Spectral Efficiency, FBMC Out Of Band (OOB) emissions declines from -31dB to -58dB. Next, in terms of Bit Error Rate (BER), 16 QAM FBMC performance decays 27dB to approximately 20dB and 4 QAM FBMC have exhibited nearly 5dB lower than 4 QAM OFDM. Whereas, for Peak to Average Power Ratio (PAPR), OFDM CCDF performance curve drops from FBMC (16dB to 12dB).
