A system like USADR AM IBOC DAB includes the FEC (forward error correction), the codec, blender, modem & interleaving section. The IBOC technology uses a PAC (perceptual audio coder) for digital compression that is expanded throughout Lucent Technology. This system will be well-matched with obtainable tuners because it uses the accessible AM &FM bands through connecting a digital sideband signal toward the typical analog signal. This kind of technology permits the broadcasting of digital audio without using new range allocations intended for the digital signal.
The IBOC (In-band on-channel) is one kind of technique used to transmit the radio signals like analog and digital on the equal frequency without assigning other range.
