OFDM A type of Multi-Carrier Modulation (MCM).
In this multiplexing mode, a channel is
divided into multiple orthogonal
subchannels. High-speed data signals are
converted into parallel low-speed subdata
streams and are modulated for transmission
on the subchannels. Orthogonal signals can
be separated at the receiver, reducing the
interference between subchannels. The signal
bandwidth on each subchannel is smaller than
the related bandwidth of the channel;
therefore, each subchannel can be regarded as
flat fading, canceling the interference
between characters. In addition, the
bandwidth of each subchannel is only a small
part of the original channel bandwidth, and
therefore channel balancing becomes easier.
