Orthogonal Frequency Division Multiplexing (OFDM) is a modulation technique used in wireless communication systems to transmit data over radio waves. It works by dividing the available spectrum into multiple orthogonal (non-overlapping) subcarriers, each carrying one constellation symbol. These subcarriers are spaced apart at precise intervals, ensuring they do not interfere with each other. OFDM is widely used in various wireless communication standards such as Wi-Fi, LTE (Long-Term Evolution), WiMAX, and 5G due to its ability to provide high-speed data transmission, robustness to interference, and efficient spectrum utilization. In this chapter, we will discuss the design of OFDM used in the air interface of the 5G networks.
