OFDM (Orthogonal Frequency Division Multiplexing) divides the channel into many smaller channels or subcarriers which are orthogonal (perpendicular) to each other. This allows for more efficient use of the available bandwidth and reduces interference from other signals. DSSS (Direct Sequence Spread Spectrum) and FHSS (Frequency Hopping Spread Spectrum) do not use subcarriers to divide the channel.
