WebThis paper presents an approach of a Matlab/Simulink-based model for Hybrid M-QAM/L-FSK (4/16 HQFM) modulation scheme with a non-coherent detection of 4-ary FSK demodulator in the presence of Additive White Gaussian Noise (AWGN) channel which maintains th ‏27 أكتوبر، 2024 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.
