ABSTRACT:
An adaptive maximum likelihood demodulator for demodulating digital radio signals on a channel which contains impairments like inter-symbol interference, frequency errors or distortion, that vary with time. The demodulator does not employ channel models to generate signal predictions but rather directly updates the signal predictions for each state without going through the intermediate step of updating a channel model.
