Which of the following modulation schemes is used for 5G cellular networks?

To determine which modulation scheme is used for 5G cellular networks, we need to consider the options available. Some common modulation schemes used in cellular networks include Frequency Modulation (FM), Amplitude Modulation (AM), Phase Shift Keying (PSK), and Quadrature Amplitude Modulation (QAM).

However, it is important to note that 5G networks primarily use a modulation scheme called Orthogonal Frequency Division Multiplexing (OFDM). OFDM is a digital modulation technique that divides the available frequency spectrum into multiple subcarriers, each carrying a small portion of the data. This allows for efficient and reliable transmission of data in 5G networks.

Therefore, the modulation scheme used for 5G cellular networks is Orthogonal Frequency Division Multiplexing (OFDM).
