OFDM

Orthogonal frequency division multiplexing (OFDM) is a transmission technique that consists of the multiplexing of a set of carrier waves of different frequencies, where each one carries information, which is modulated in QAM. or in PSK.

MIL modes using OFDM modulation that are often found in the amateur radio bands are presented here

CIS-60

This CIS MIL mode is also known as Russian High Data Rate modem
