Detailed explanation-1: -Explanation: WiMAX physical layer uses orthogonal frequency division multiplexing as it provides simplified reception in multipath and allows WiMAX to operate in NLOS conditions.
Detailed explanation-2: -Introduction to 802.11a OFDM The 802.11a standard uses the same core protocol as the original standard, operates in 5 GHz. band, and uses a 52-subcarrier orthogonal frequency division multiplexing (OFDM. OFDM is an alternative tranmission scheme to DSSS and FHSS.)
Detailed explanation-3: -Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation.
