Doubly differential modem turns out to be a promising technology for coping with unknown frequency offsets with the pay of signal-to-noise ratio (SNR).
These solutions include for the first time digital-to-analog/analog-to-digital conversion and embedded multi-gigabit mixed signal modem requiring no external processing.
The result of this investigative effort is an optimized modem signal processing architecture that is applicable to a variety of digital phase modulation schemes and that utilizes a combination of these techniques for signal generation, detection, and synchronization.
A new modem circuit technique is proposed for multilevel signal transmission to utilise the transmission bandwidth efficiently in bandwidth-constrained voice-band channels.
So modem receiver demodulate QAM based signal and needs optimum architecture that fully uses these transmission feature.
