Coherent am demodulator using a weighted lsb/usb sum for interference mitigation
Abstract
The device for processing radio AM signal method, comprising the following steps: The receiving comprising an upper part side-band and lower sideband part AM radio signals, demodulates the upper part side-band and lower sideband part in order to generate the lower sideband signal of upper side-band signal and demodulation of demodulation, responded the upper side-band the lower sideband signal of signal and demodulation of power and weighting demodulation in turn to generate a weighted demodulation upper side-band signal and a weighted demodulation lower sideband signal, and combination of weighted demodulation upper side-band signal and a weighted demodulation lower sideband signal in order to generate the output signal. The further - comprising a processing AM radio signals to for of the method for demodulator, and demodulator's and receiver.
