DRM
DRM can deliver FM-comparable sound quality on frequencies below 30 MHz and beyond
up to VHF band that enables very-long-distance signal propagation.
DRM uses in-band on-channel (IBOC) technology and can operate in a hybrid mode called
Single Channel Simulcast.
DRM has been designed especially to use portions of older AM transmitter facilities such as
antennas, avoiding major new investment.
DRM is robust against the fading and interference.
The encoding and decoding is performed using digital signal processing, so that a cheap
embedded computer with a conventional transmitter and receiver can perform.
DRM can transmit other data besides the audio channels.
