Topic: Discrete Multitone Modulation
Discrete Multitone (DMT) transmission uses the fast Fourier transform (FFT) to convert constellations consisting of complex data coordinates representing binary data to discrete pulses. A digital to analog converter converts the pulses to a sinusoidal wave shape suitable to transmission over twisted copper pairs. At the receiver the waveform goes through an analog to digital converter (ADC) and the pulses are recovered. An inverse FFT is performed to recover the complex data coordinates and the complex coordinates are mapped to (hopefully) the original binary data at the receiver. DMT is the basis for ADSL technology.
