WebNov 20, 2024 · Coherent demodulation of FSK signal can be effected using (a) correlation receiver (b) band pass filters and envelope detectors (c) matched filter (d) discriminator … WebNow let's say we added AWGN (N) and Rayleigh fading (h) as well. Rx= h*x + N; Now when I tried to detect it on the receiving side I will have to divide this entire Rx by an h, well that makes sense. My entire graphs for the BER curve match non-coherent detection for FSK. It exactly matched the theory, Eb/N0 vs. BER for BFSK over Rayleigh Channel.
WebThe asynchronous demodulation can be employed readily for both the amplitude shift keying (ASK) and frequency shift keying (FSK) formats. In the FSK case, the heterodyne receiver uses two separate branches to process the 1 and 0 bits whose carrier frequencies, and hence the intermediate frequencies, are different.
