The future generations of wireless communication’s main aim is to provide increasing and required demands of the users, mainly focusing on the flexibility, bandwidth, low latency, spectral efficiency. Orthogonal frequency division multiplexing (OFDM) is used in 4G communication systems. To reduce the drawbacks of 4G moved in 5G communication systems in which Generalized frequency division multiplexing (GFDM) is worn. In this manuscript, mainly learn the modulation techniques used for 5G communications like GFDM and OFDM. These modulation techniques are operated in additive white Gaussian noise channel (AWGN). Fast Fourier Transform (FFT) and Inverse Fast Fourier transform (IFFT) are used for performance evaluation and analysis in OFDM. In GFDM, zero forcing receiver (ZFR) is used which represents a crucial task in digital broadcasting. When ZFR is considered the GFDM performs better interference.
