What is OFDMA?

Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user version of the Orthogonal Frequency-Division Multiplexing (OFDM) digital modulation scheme. In OFDMA, multiple users can transmit simultaneously, each using a subset of the subcarriers. It is commonly used in 4G and 5G cellular networks, WiMAX, and WiFi (IEEE 802.11ax) to enhance data rates, improve spectral efficiency, and provide flexible bandwidth allocation.
