WebJan 27, 2024 · Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation scheme, which was invented to cope the frequency selectivity in communication channels. The xDSL network, which delivers high speed data service over the existing telephony networks, adopted OFDM as the modulation scheme from the beginning.
