Lecture
Discrete Multitone Modulation
Description
This lecture revisits the concept of discrete multitone modulation, focusing on the ADSL trick of using interval indicators instead of lowpass filters, the DTFT of interval signals, and the complex output signals in subchannel modems. It also explores how to improve the output signal and discusses ADSL transmitters and specifications, such as maximum frequency, QAM capabilities, and theoretical throughput.
