OFDM

Orthogonal Frequency-Division Multiplexing (OFDM) is a digital modulation technique used in telecommunications to transmit data over multiple closely spaced orthogonal subcarriers. It efficiently divides a high-rate data stream into multiple lower-rate streams transmitted simultaneously, improving resistance to frequency-selective fading and interference. OFDM is widely implemented in modern wireless standards like Wi-Fi (IEEE 802.11a/g/n/ac/ax), 4G LTE, and 5G NR for high-speed data transmission.

Also known as: Orthogonal Frequency Division Multiplexing, OFDMA, Multi-carrier modulation, Frequency-division multiplexing, FDM
🧊Why learn OFDM?

Developers should learn OFDM when working on wireless communication systems, such as designing or optimizing Wi-Fi routers, cellular networks, or IoT devices, as it enables robust and high-bandwidth data transfer in challenging environments. It's essential for roles in telecommunications engineering, signal processing, and embedded systems where understanding modulation schemes is critical for performance and compliance with standards like 5G.
