 Orthogonal Frequency Division Multiplexing (OFDM) Explained
Orthogonal Frequency Division Multiplexing (OFDM) is a wireless technology patented in 1970 that runs on the principle of transmitting data by dividing the data stream into multiple parallel bit streams that have a much lower bit rate and using these sub-streams to modulate several carriers.
Although OFDM has been around since the 1960s, only recently has it been recognized as an outstanding method for high speed, bi-directional wireless...
