Fast and accurate demodulation of wideband signals

Amplitude demodulation is a classical operation used in signal processing. For long time, its effective applications practice have been limited to narrowband signals. In this work, we generalize amplitude wideband We pose as recovery problem of an oversampled corrupted and introduce special iterative schemes belonging the family alternating projection algorithms solve it. Sensibly chosen structural assumptions on outputs allow us reveal high inferential accuracy method over rich set relevant This new approach surpasses current state-of-the-art techniques apt signals computational efficiency by up many orders magnitude with no sacrifice quality. Such performance opens door for procedure contexts. particular, makes online large-scale offline data processing feasible, including calculation modulator-carrier pairs higher dimensions poor sampling conditions, independent bandwidth. illustrate utility specifics using natural speech synthetic
