Broadband receiver of narrowband signal based on the cascaded stochastic resonance

Tongxin xuebao, 2015
To improve the demodulation gain of traditional narrowband receiver,a narrowband signal receiving method of broadband based on cascaded stochastic resonance is proposed.On one hand,the noise in the signal is converted to the signal energy by the ...

Satellite Signal Demodulation Using Kalman Filter

, 2017
Satelitski komunikacijski sustavi koriste QPSK demodulaciju u svrhu rekonstrukcije poslanog signala. Signal koji dolazi na prijamnik, prolaskom kroz AWGN kanal, podložan je utjecaju Gaussovog bijelog šuma.
